Your swimming pool has a leak in it. Right now there is 70 gallons of water in it. The water is leaking at a rate of 4 gallons a minute. How long do you have until you or swimming pool is completely empty? (Write an expression to represent the problem)

about 17 and a half minutes until it completly empty.

Step-by-step explanation:

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)

i think its a and d
