What are the slope and the y-intercept of the linear function that is represented by the graph?
On a coordinate plane, a line goes through points (negative 3, 0) and (negative 2, 4).
The slope is 3, and the y-intercept is 9.
The slope is 3, and the y-intercept is 12.
The slope is 4, and the y-intercept is 9.
The slope is 4, and the y-intercept is 12.
Answer: The slope is 4 and the y-intercept is 12.
Step-by-step explanation:
(-3,0) and (-2,4)
find the difference in the Y values 0-4=-4
find the difference in the v- values -3-(-2) =-1
Divide the y difference by the x difference -4/-1 = 4 so 4 is the slope
Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept
4= 4(-2) + b
4 = -8 + b
+8 +8
b= 12 so the y intercept is 12
now the equation will be like y = 4x + 12
(-3,0) and (-2,4)
find the difference in the Y values 0-4=-4
find the difference in the v- values -3-(-2) =-1
Divide the y difference by the x difference -4/-1 = 4 so 4 is the slope
Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept
4= 4(-2) + b
4 = -8 + b
+8 +8
b= 12 so the y intercept is 12
now the equation will be like y = 4x + 12

(25 points!!!!) draw the graph of the area bounded by these inequalities
Step-by-step explanation:
To draw the graph, follow these steps:
Graph the lines using points from the equations. (the blue line shown should be dotted, unfortunately I cannot do that in the program I used)Determine which direction the inequalities are correct. Find the boundary given.The three inequalities given form a triangle.
The first equation, y ≤ 2x + 5, has a y-intercept at (0, 5) and a point at (-2, 1).
The second equation, y < -3x + 10, has points at (3, 1) and (2, 4).
Use two points to draw the lines.
After the lines are drawn, determine which side of the line the inequality works on. You can do this by testing points that are not on the line.
I will test each inequality using (0, 1):
y ≤ 2x + 5
0 ≤ 2 + 5
This is correct, so the inequality for y ≤ 2x + 5 will be shaded towards (0, 1).
y < -3x + 10
0 < -3 + 10
This is correct, so the inequality for y < -3x + 10 will be shaded towards (0, 1).
0 ≤ 1
This is correct, so the inequality for 0 ≤ y will be shaded upwards towards (0, 1).
The end result of this graph is all three inequalities being shaded (inwards).
The solution is a triangle with points at (1, 7), (3.33333, 0), and (-2.5, 0).

Amy is creating an enlargement of the following image for an art gallery.
She needs the enlargement to follow the scale of ¼ of a foot to 3 feet. This will result in an image with a length of 8 feet and width of 6 feet.
what is the unit rate of area in square feet of the enlargement image per square foot of area of the original image?
A. 144 square feet per square foot
B. 48 square feet per square foot
C. 16 square feet per square foot
D. 32 square feet per square foot
Answer:
A
Step-by-step explanation:
Since all of the dimensions are being expanded by a scale of 1/4 of a foot to 3, or an increase of a factor of 12, the area is being increased by 12*12=144 times, or choice A. Hope this helps!
The unit rate of area in square feet of the enlargement image per square foot of the area of the original image is 144 square feet.
The scale of 1/4 of a foot = 3 feet
So scale of a foot = 3*4 =12 feet
What is a scale factor?A scale factor is a factor by which the dimension of an object is enlarged or diminished.
So, the area of the enlarged image = 12 feet*12 feet
The area of the enlarged image =144 square feet
Hence, the unit rate of area in square feet of the enlargement image per square foot of the area of the original image is 144 square feet.

Find the value of x posting picture
Answer:
x = 9; Option C
Step-by-step explanation:
If p ║q, we are provided with the following properties;
Same Side Interior / Exterior ∠s ⇒ supplementary,
Alternate Interior / Exterior ∠s ⇒ ≅,
Corresponding ∠s ⇒ ≅
If we are focusing on the measure of two alternate interior angles, say a and b, we can assign them as such;
a ⇒ 9x + 8, and b ⇒ 15x - 46
m∠ a = m∠ b ⇒ provided they are alternate interior ∠s,
9x + 8 = 15x - 46 ⇒ Add 46 on either side of equation,
9x + 54 = 15x ⇒ Subtract 9x from either side,
54 = 6x ⇒ Divide either side by 6,
Solution; x = 9
pls solve 2(3 - x) -12 + 4x = -3x -9
Answer:
x = -3/5
Step-by-step explanation:
2(3 - x) -12 + 4x = -3x -9

Answer:
g(u) = -3/2 u + 1/4
Step-by-step explanation:
Solve for v
-12u +3 = 8v +1
Subtract 1 from each side
-12u +3-1 = 8v +1-1
-12u +2 = 8v
Divide each side by 8
-12u/8 +2/8 = 8v/8
-3/2 u + 1/4 = v
v = -3/2 u + 1/4
g(u) = -3/2 u + 1/4

Which of the following is the graph of f(x) = 3 sin (2x)? (2 points)
Step-by-step explanation:
please make me brainlestTHANK UThe graph which passes through the (0,0) point is the graph of f(x) = 3 sin (2x)
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The general form of a sine function is;
y = Asin(Bx+C) +D
where;
A is the amplitude.
B is the frequency.
From f(x) = 3 sin (2x), we can say that;
A = 3
This implies that the graph has waves that has height from -3 to 3.
B = 2
This means that there are two waves between 0 and 2π with the period of the function being π.
Hence, the graph goes through the (0,0) point.
