Answer:
x=5
Step-by-step explanation:
9(3x-16)+15=6x-24
27x-144+15=6x-24
27x-129=6x-24
21x=105
x= 5
Answer:
y = 2/3x - 13
Step-by-step explanation:
We have a slope of 2/3 and a point (9, -7)
The point slope form of a line is
y-y1 = m(x-x1)
y--7 = 2/3 (x-9)
Distribute
y+7 = 2/3x - 6
Subtract 7 from each side
y+7-7 = 2/3x -6-7
y = 2/3x - 13
This is in slope intercept form.
