Is this right ,and if not respond quickly

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
