Answer:
y = -8x + 4
Step-by-step explanation:
Using the y = mx +b for the slope intercept form, the m stands for the slope and the b stands for the y-intercept.
In this case, the slope is -8 and the y-int is 4 so we naturally plug those in
37,800 since it depreciates by 8% of the original price each year
Find the gradient
m = y2-y1 / x2-x1
m = 4-(-2) / 3-(-3)
m = 6 / 6
m = 1
Insert the values of one of the points into y=mx+c to find c (choosing point (3,4)):
y = mx + c
4 = 1(3) + c
c = 4 - 3
c = 1
Therefore, the equation is:
y = x + 1
