AIM: Graphing Slope Intercept Form

SLOPE INTERCEPT FORM

y = mx + b

m = slope (how the points Move)

b = y-intercept (where the Bomb hits the target)

To graph in slope-intercept form

1. Write the equation in y = mx + b form by solving for y

2. Identify slope as m (number multiplied to x)

3. Identify y-intercept as b (number without the x)

4. Make a point at b on the y-axis

5. Move from that point m rise/run for the next point.

6. Continue until you can connect the points in a line through the coordinate plane.

Example y = 5x + 3

slope = 5 = 5/1

5 rise = 5 up

1 run 1 right

y-intercept = 3

Example y = 5x + 3

slope = 5

y-intercept = 3

Example y = -2x

slope = -2

y-intercept = 0

Example y = -2x

slope = -2

y-intercept = 0

slope =

y-intercept = -2

y 3

4x 2 Example

3

4

slope =

y-intercept = -2

y 3

4x 2 Example

3

4

Example 2y = 4x - 6

2y = 4x - 6

Divide by 2.

y = 2x - 3

Slope = 2

y-intercept = -3

Example 2y = 4x - 6

2y = 4x - 6

Divide by 2.

y = 2x - 3

Slope = 2

y-intercept = -3
