Slope-Intercept Form

1. Y = 2x +7

Y-intercept = (2,7); slope = 1/2

Y-intercept = (0,7); slope = 2

Y-intercept = (2,0); slope = 7

2. Y = x - 6

Y-intercept = (0,-6); slope = 1

Y-intercept = (1,-6); slope = 0

Y-intercept = (0,-1); slope = 6

3. Y=-3x + 8

Y-intercept =(0,8); slope = -3

Y-intercept = (0,-8); slope = 3

Y-intercept = (0,-3); slope = 8

4. Y = 5x - 3

Y-intercept = (0,3); slope = 1/5

Y-intercept = (0,-3);slope = 5
