Answer:
B.
Step-by-step explanation:
The lines positioning shows a negative slope already, so it cant be C or D
Slope is a rise over run basis. You can check this just from points alone, the line would be much steeper if the slope was -2.

find the equation of the linear function represented by the table below in slope-intercept form. picture of table is below
Answers
Answer:
y = 3x+1
Step-by-step explanation:
Well, slope intercept form is y =mx+b, and to find the slope, you have to take two of the examples for y, and divide it by 2 examples of the x, like so:
7- (-5) / 2- (-2) which is 12/4 which is 3, so the slope is 3.
we now can make the first part of the equation:
y = 3x + b
Now we just need "b". To find b, just substitute the x and y values for two values shown on the chart, such as -2 and -5. (They have to be on the same row).
-5 = 3x-2 + b
you get:
-5 = -6+b
which is equal to:
b = 1
So, putting b back in the equation, you get:
y = 3x+1

Step-by-step explanation:
Range is all possible y values that the graph covers.

This process is illustrated in the attachment.

To find f(x) = n, reverse the process. Locate n on the f(x) axis, then move horizontally to the curve, then vertically to the x-axis. That is the value of x you're looking for.

Since the given relation is proportional, the value of s multiplied by the constant of proportionality will be the value of P
we can write the above statement as:
s * k = P (where k is the constant of proportionality)
putting some given proportional values of s and P
2 * k = 8
k = 8 / 2
k = 4
Now that we have the constant of proportionality, we can use it in the equation we just made
s * k = P
s (4) = P
4s = P
This is the relationship between s and p, represented by an equation

Write an equation of the line passing through the point A(3,−4) that is parallel to the line y = −x+8.
Answers
Answer:
y = -x -1
Step-by-step explanation:
The x- and y-coordinates will be the same for the parallel line, so we only need to find the constant that needs to replace the +8 in the given equation.
y = mx +b
y = -x +b . . . . . with the coefficient of x filled in
-4 = -(3) +b . . . with the given point filled in
b = -1 . . . . .add 3 to both sides

Answers
Answer:
C: The Same Line
Step-by-step explanation:
So to start we need to first know what makes lines parallel or perpendicular. Two parallel lines will have the same slope, but different y-intercepts because we know they never cross. Two perpendicular lines will have opposite-reciprocal slopes, because we know that they intersect at a right angle.
Then, we need to know the slope-intercept form of an equation. The slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept. We can see that neither equation is in this form, so we have to convert it.
Starting with the first, (I assume despite the typo) we have [tex]25y+10x= 200[/tex]
So we need to isolate the [tex]y[/tex] from everything else.
First, we'll subtract [tex]10x[/tex] from both sides of the equal sign to get [tex]25y=-10x+200[/tex]
Second, we'll divide both sides by [tex]25[/tex] to get [tex]y=-\frac{2}{5} x+8[/tex]
This means that [tex]-\frac{2}{5}[/tex] is the slope and [tex]8[/tex] is the y-intercept of the first line.
Now onto the second we have [tex]5y+2x=40[/tex] so we're going to follow the same steps to isolate [tex]y[/tex].
First, we'll subtract [tex]2x[/tex] from both sides to get [tex]5y=-2x+40[/tex]
Second, we'll divide both sides by [tex]5[/tex] to get [tex]y=-\frac{2}{5}x +8[/tex]
This means that [tex]-\frac{2}{5}[/tex] is the slope and [tex]8[/tex] is the y-intercept of the second line.
Since both of the lines have a slope [tex]-\frac{2}{5}[/tex] we know that they are parallel, so we need to check to check if they're the same by looking at the y-intercept. We can see that [tex]8[/tex] is the y-intercept of both lines, so they would be the same line.
