Given Slope and Intercept

100

Write in slope-intercept form.

Slope = -1/4

Y-Intercept = -1

y = -1/4x - 1

200

Write in slope-intercept form.

Slope = 5/4

Y-Intercept = -4

y = 5/4x - 4

300

Write in slope-intercept form.

Slope = 4

Y-Intercept = -2/3

y = 4x - 2/3

400

Write in slope-intercept form.

Slope = 3/7

Y-Intercept = 2/9

y = 3/7x + 2/9

500

Write in slope-intercept form.

Slope = 1

Y-Intercept = 0

y = x

Solve for x

100

3x + 5 = 10

x = 5

200

6x + 6 = 42

x = 6

300

25 + 10x = 105

x = 8

400

15x + 10 + 5x = 210

x = 10

500

5(3x + 5) = 70

x = 3
