a
step-by-step explanation:
y = 5x + 17
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
-12 > a
-11 > 1 + a
subtract 1 from each side
-11 -1> 1 -1+ a
first one because it can't have a fraction in it
