Question

A line goes through the point (5, −7) and has slope = −3. What is the y-intercept?

Answer 1

To find the y-intercept, we must plug in the given point and the given slope into slope-intercept form*.

`-7 = -3(5) + b\\\\-7 = -15 + b\\\\8 = b`

The y-intercept is (0, 8).

Answer 2

the y intercept is 8

Explanation:

5,-7. 5x3=15+-7=8
