Slope-Intercept Form: y = mx + b

3. Point-Slope Form
Slope
Ordered pair

4. Point-Slope Form We know the point (-2, -2), so x1 = -2 and y1 = -2
1. Write the equation in Point-Slope Form of the graph below:
(x1, y1) = (-2, -2)
We know the point (-2, -2), so x1 = -2 and y1 = -2
(x, y)
We know the slope is 2/3
Plug it into the Point-Slope Form:

5. Write an Equation in Point-Slope Form Given a Point and a Slope
y + 3 = 4(x + 1)
5. (-10, 0); Slope = 2
y = 2(x +10)
6. (-4, 3); Slope = -6
y – 3 = -6(x +4)
