Question

A line passes through the points 3, 0 and 4, 1. what is the y-intercept of the line
​

Answer 1

9514 1404 393

Answer:

(0, -3)

Explanation:

The slope is the same for any segment of the line. The slope from (0, y) to (3, 0) is the same as from (4, 1) to (3, 0).

Δy/Δx = (y -0)/(0 -3) = (1 -0)/(4 -3)

y = -3(1/1) = -3 . . . . . multiply by -3

The y-intercept is (0, -3).
