Question

A coordinate plane with a line passing through (negative 4, 3), (0, 1), and (2, 0).


What are the slope and y-intercept of the linear function graphed to the left?

slope: –2; y-intercept: 2
slope: ; y-intercept: 1
slope: ; y-intercept: 2
slope: 2; y-intercept: 1

Answer 1

Slope = (0 − 1)/(2 − 0) = −1/2.
y-intercept = the y-value at x = 0, which is 1.

So slope = −1/2 and y-intercept = 1.
