3ab + 3a + 2b + 2
3a(b+1)+2(b+1)
(b+1)(3a+2)
y = 5x + 17
step-by-step explanation:
a perpendicular line will be the opposite reciprocal slope of the given equation. the slope given is -1/5 so the opposite reciprocal is 5
find b:
7 = 5 (-2) + b
7 = -10 + b
17 = b
write equation
i think the length is 12 and the width is 17
