Subtracting a polynomial from itself... results in another polynomial because 0 is a...

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

y = 5x + 17

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
