Question

Solve each equation for y by rewriting it in slope-intercept form (y = mx + b). Also state the slope and y-intercept of each.

2x - 4y = 8

Answer 1

Explanation:

So we just want to get y by itself

2x - 4y = 8

4y = 2x - 8

y = (2/4)x - 2

y = (1/2)x - 2

In this form the y intercept and slope are easy to see. the slope is m and y intercept is b.

slope = 1/2

y intercept = -2
