1. Graphing

2. Information Slope intercept form: y = mx + b M = slope B = y-intercept
Identify the slope and y-intercept
Y = -2/3x + 3
Y = 2x – 4
Y = 4x + 3

3. Identify the slope and y-intercept
Y = -2x + 5
Y = 4x - 8
Y = 3/4x + 7
Y = -3/5x - 28

4. Graph
Y = -x + 1
3x – 2y = 6
Y = 4x

5. Graph
Y = -3x
2x – 5y = 15
Y = 2x + 3

6. Identify the graphs
Y = 2x Y = -2/3x – 1 Y = 3x + 2

7. Horizontal/Vertical lines
Horizontal: line crosses y-axis.
Vertical: line crosses x-axis
Ex: x = 3, x = -2
y = 2, y = -5

8. Vertical/Horizontal Graphs-st
Graph the following
X = 2
Y = -4
X = -1

9. Slopes of Parallel and Perpendicular lines
Find Parallel slope
Use same slope
Find perp. Slope
Use opposite reciprocal of slope.
2x – 5y = 15
Y = 4x + 10

10. Find Parallel/perp. slope
Y = -1/4x + 1
Y = -3x + 1
