1. Writing Linear Equations
Objective: Students will learn a variety of ways to find the slope and y-intercept. They will use those to construct an equation.

2. Write equation given slope/intercept
Use slope intercept form y = mx + b
Slope: 1, y-int: 3
Slope: 2/3, y-int: -8
Slope: -8, y-int: 5

3. Write equation given slope/intercept
Slope: -3, y-int: 12
Slope: 3/2, y-int: 3
Slope: 5/6, y-int: -6
Slope: -1, y-int: -20

4. Equation from ordered pairs-t,st.
(-2, 13) (0, 1)
(0, -5) (3, -3)
(0, 9) (3, 15)
(0, -3) (2, -2)

5. Write equation from graph
Find slope
Find y-int
Write equation

6. Write equation from graph-st
Blue:
Red:
Green:

7. Equations for parallel/perpendicular lines-st
Write equation of a line parallel to y = 2x + 1 and passes through (0,4)
Write equation of a line perpendicular to y = -x – 4 and passes through (0,7)

8. Equations for parallel/perpendicular lines
y = 4x – 8 and passes through (0,2)
Y = 1/2x + 2 passes through (0, -3)
perpendicular
y = -5x + 1 passes through (0, -9)
Y = 2/3x + 2 passes through (0, 2)
