Answer:
8 = r
Step-by-step explanation:
69 = 9r -3
Add 3 to each side
69+3 = 9r -3+3
72 = 9r
Divide each side by 9
72 / 9 = 9r/9
8 = r
Answer:
y = -8x + 43
Step-by-step explanation:
Parallel lines have the same slope. The line g is -8x - 1 and has slope -8.
To find a line parallel to it, substitute m= -8 and the point (5,3) to determine th equation.
y - 3 = -8(x - 5)
y - 3 = -8x + 40
y = -8x + 43
