The correct answer is Choice A.
You can see from the graph that the y-intercept is 50 because it cross on the left at 50.
To find the slope, we can use the following two points (0, 50) and (20, 110). This will give a slope of 3.
Put the 50 and 3 together and you will have the equation:
y = 3x + 50
I think it would be 72+4x=400
400-72= 328
328/4= 82
So the answer would be 82=x
