answer: ouch. thats difficult
step-by-step explanation:
a.
step 1 distribute 2 to every term in the parentheses
step 2 add 10 on both sides of the equal sign
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
