Answer:
D i think
Step-by-step explanation:
If the x-intercept is 7, then the coordinate is 7 along the x-axis and 0 up the y-axis, so the coordinate is (7,0). We now have the two points (4,2) and (7,0).
You can find out the slope of any line using the general equation:

(0-2)/(7-4) = -2/3
The slope of the line is -2/3x.
X-intercept: (-9,0)
y-intercept: (0,3,)
1st- gained lost 800, gained 900
2- lost 400- gained 600
so in all she lost 1200
but then gained 1500
