What is the y intercept of the liner function that contains the points (4,1) (-3, -20)

Step-by-step explanation:

To get the y-intercept, we need to get the slope first

Slope = y2-y1/x2-x1

Slope = -20-1/-3-4

slope = -21/-7

Slope = 3

Get the y-intercept. Substitute m = 3 and any point say (4, 1) into the expression y = mx+c

c is the y-intercept

1 = 3(4) + c

1 = 12 + c

c =1-12

c = -11

Hence the y-intercept is -11

i dont understand the question? ?
