Download y = mx + b y = 2x

y = mx + b
______________________________________________
m= slope
b= y-intercept
 Writing equations in slope intercept form given a
Steps: 1. Plug in the slope (m).
ex: m= 2, b = -9
.
y = 2x - 9
2. Plug in the y-intercept (b).
 Writing equations in slope intercept form given a
Steps: 1. Plug in your slope (m).
ex: m = -3, (-2, 1)
2. Plug in your point (x,y).
.
3. Solve for b.
4. Plug in the slope (m) and the y-intercept (b).
 Writing equations in slope intercept form given
.
Steps: 1. Find the slope using the two points given.
ex: (–5, 9) and (1, 3)
2. Use the slope and first point to solve for b.
3. Plug in the slope and y-intercept.
 Writing equations in slope intercept form given the
Steps: 1. Move x to the right side of the equation.
ex: 3x – 8y = 16
2. Isolate y.
 Writing equations in slope intercept form given the
Steps: 1. Distribute the slope.
ex: y + 9 = -6(x – 5)
2. Combine like terms.
3. Isolate y.
 Writing equations in slope intercept form given a
Steps: 1. Identify the slope (m).
