200

Find the x intercept 3x + 4y = 12

4

300

Find the slope 7x - 8y = 56

7/8

400

Find the y intercept 12x - 7y = 84

-12

500

Find the x intercept, y intercept and the slope -8x + 4y = 24

x interept = -3 y intercept = 6 slope = 2

Slope Intercept Form

100

What is slope intercept form?

y = mx + b

200

What is the y intercept? y=5x - 8

-8

300

What is the slope? y= 3x + 2

3

400

What is the slope and y intercept? y=-4x + 7

slope = -4 y intercept = 7

500

write the equation in slope intercept form given Slope = -7 y intercept = -3

y = -7x - 3

Standard to Slope Intercept

100

5x + 10y = 20

y = -1/2x + 2

200

6x - 3y = 24

y=2x - 8

300

2x + 5y = 20

y = -2/5 + 4

400

5x - 6y = 60

y = 5/6 - 10

500

3x - 5y = 30

y = 3/5x - 6

Finding the y intercept

100

Find the x and y intercept 3x + 12y = 12

y intercept = 12

200

5x + 2y = 10

y intercept = 5

300

Find the x and y intercept 6x + 3y = 18

y intercept = 6

400

4x + 8y = 16

y intercept = 2

500

7x + 3y = 21

y intercept = 7

Random

100

Simplify 8x + 3x - 2x =

9x

200

Solve for x 3(x + 2) = 18

x = 4
