Answer:
(y - y') = m ( x - x') [m = slope]
y - (-4) = 2/3 (x - 9)
(y +4) = 2/3 (x - 9)
3(y +4) = 2(x - 9)
3y +12 = 2x - 18
2x - 3y - 18 - 12 =0
2x - 3y - 30 =0
hope it helps ☺️☺️
The equation of the line passing through (9, -4) having slope = -2/3 will be y = (-2/3)x + 2
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
y = mx also represents direct proportionality. We can write [m] as -
m = y/x
OR
y₁/x₁ = y₂/x₂
Given is a line passing through (9, -4) having slope=-2/3.
The general equation of a straight line is -
[y] = [m]x + [c]
Now -
m = - 2/3
and
- 4 = -2/3 x 9 + c
- 4 = - 6 + c
c = - 4 + 6
c = 2
The equation will be -
y = (-2/3)x + 2
Therefore, the equation of the line passing through (9, -4) having slope = -2/3 will be y = (-2/3)x + 2

Slope of the line shown is option C. 3.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Given is a line.
The two points that the line passes through is given.
(4, 8) and (2, 2)
Slope of a line passing through two points can be found as,
Slope = (Change in y coordinates ) / (Change in x coordinates)
Here the points are (4, 8) and (2, 2),
Slope = (2 - 8) / (2 - 4)
= -6 / -2
= 3
Hence the slope of the line given is 3.

Suppose 24 is 2%. What is 100%?*
Answer:
1200
Step-by-step explanation:
If 24 is 2%, 100% would be 1200 because if you multiply 2 by 50 you get 100% so you multiply 24 by 50 which is 1200
Answer:
20.
Step-by-step explanation:
The strategy here is to see how many times the "percent number" (in this case, 25) goes into 100, and then count by that number until we reach 100-the whole thing. Here, we're told that 25% of a number is 5. So, to find 100% of the number, we count by 25s up to 100: 25, 50, 75, 100. 100% is 20.
Determine whether each statement is true or false:
a. Adding a multiple of one column of a square matrix to another column changes only the sign of the determinant.
b. Two matrices are column-equivalent when one matrix can be obtained by performing elementary column operations on the other.
c. If one row of a square matrix is a multiple of another row, then the determinant is 0.
Answer:
a. False
b. True
c. True
Step-by-step explanation:
The statement a is false and the other two statements are true. Adding a multiple of one column not only changes the sign of the determinant but also the variables are changed. When two rows of square matrix are equivalent then the determinant is zero which means when one row is multiple of another row the determinant is zero.

Whats is the distance between the ferris wheel and the merry-go-round? Ferris wheel on the coordinate plane is (-9,6) and the location of the merry-go-round is (10,6)
Answer:
19 units
Step-by-step explanation:
use distance formula: d = [tex]\sqrt{(x_2-x_1)^{2}+(y_2+y_1)^{2}}[/tex]
x₂ = 10
x₁ = -1
y₂ = 6
y₁ = 6
now plug in

Answer:
x > -6.33
Step-by-step explanation:
-3x + 4 < 25
-3x + 4 - 4 < 25 - 4
-3x < 19
-3x/3 < 19/-3
x > -6.33
Answer:
x> -7
Step-by-step explanation:
Subtract 4 from both sides:
−3x+4−4<25−4
Simplify:
−3x<21
Multiply both sides by −1 (reverse the inequality)
(−3x)(−1)>21(−1)
Simplify again:
3x>−21
Divide both sides by 3
(3x/3) >(−21/3 )
Simplify again to get the result!
