Which function below has the lowest y intercept? f (x) graph going through (0, 5) and (2, 1) g (x) Kyle started the summer having read 3 books but plans to read 6 books per month over the summer. h (x) h (x) = 3x + 4

First find the slope of f (x).

m = (y2-y1) / (x2-x1)

m = (1-5) / (2-0)

m=-4/2

m=-2

y=-2x+b, using (2,1) we can solve for the y-intercept, "b"

1=-2 (2) + b

1=-4+b

5=b

y=-2x+5

So f (x) has a y-intercept of 5

g (x) = 6m+3

So g (x) has a y-intercept of 3

h (x) = 3x+4

So h (x) has a y-intercept of 4

Then g (x) has the lowest y-intercept of just 3.
