(0,-16); (1, -12)

Step-by-step explanation:

4x-y=16

plug each ordered pair in to find out if it works

4(-2)-(-8)=16

two negatives make a positive

-8+0=16

-8 does not equal 16

4(-1)-(20)=16

-4-20=16

-24 does not equal 16

4(0)-(-16)=16

two negatives make a positive

0+16=16

16=16

4(1)-(-12)=16

two negatives make a positive

4+12=16

16=16

4(3)-(4)=16

12-4=16

8 does not equal 16

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

it would take 7/10 of an hour too fill the pool.
