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
