Aubrey filled her pool 0.9 of the way with water. Water evaporated from the pool at a rate of 7.5 ft^3 per day. For how many days, d, will there be more than 30 ft^3 of water in the pool? Part A. Write an inequality that fits this situation.
Part B. What is the solution to the inequality?

step-by-step explanation:

based on the question i am guessing that it is a typo for abc

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
