The point-slope form of the equation of a line is
y - y1 = m(x - x1)
where m is the slope, and (x1, y1) is a point on the line.
We are given two points, so we can find the slope.
slope = m = (y2 - y1)/(x2 - x1) 
The slope of this line is
m = (-3 - 7)/(5 - (-15)) = -10/20 = -1/2
Since every choice has a 7 and a 15, we now use point (-15, 7) and slope -1/2.
y - y1 = m(x - x1)
y - 7 = -1/2(x - (-15))
y - 7 = -1/2(x + 15)

Answer:
9 weeks.
Step-by-step explanation:
First, find how many dollars Navid needs to save. 
288-72= 216
Then, divide how much money that is needed by the number of dollars that are saved per week. 
216/24= 9
Then tie it up into an equation: 
(288-72)/24= x
x=9
