Answer:
-2/3
Step-by-step explanation:
We are trying to find the slope given two points
m = ( y2-y1)/(x2-x1)
= ( -1-3)/( 2- -4)
= ( -1-3)/( 2+4)
-4/6
-2/3
9(3x - 16) + 15 = 6x - 24
First distribute 9 to 3x and -16.
27x - 144 + 15 = 6x - 24
Combine like terms. (-144 + 15)
27x - 129 = 6x - 24
Get the variable, x, on one side of the equation. You can do this by subtracting 6x from both sides.
21x - 129 = -24
Add 129 to both sides to isolate x.
21x = 105
Divide 21 off of both sides to find the value of x.
x = 5
You can plug x into the equation to check your answer.
9(3 x 5 - 16) + 15 = 6(5) - 24
6 = 6
