1. Slope Intercept Form & Graphing

2. Definition - Intercepts
The x-intercept of a straight line is the x-coordinate of the point where the graph crosses the x-axis.
The y-intercept of a straight line is the y-coordinate of the point where the graph crosses the y-axis. y

3. What is the y-intercept?-4 1 -3 -2 2 3 -1 5 4 -5
What is the y-intercept?
y-intercept = 3
y-intercept = -4
y-intercept = -3
y-intercept = 5
y-intercept = 0

5. Slope is Rise over Run. The Denominator The Numerator
Tells you to “rise” up or down
Positive = Up
Negative = Down
The Denominator
Tells you how far to “run” left or right
Positive = Right
Negative = Left.

7. Finding the slope and y-intercept
State the slope and
y-intercept of:
y = 3x + 2
BACK

8. y = 3x + 2 Y
Slope = 3/1
y-intercept= 2 X
Up 3 and Right 1
BACK

9. y = -2x + 3 Y
Slope = -2/1
y-intercept= 3 X
Down 2 and Right 1
BACK

10. y = 3x -2 Y
You try this one X
BACK

11. y = 3x -2 Y X
BACK

12. Slope = -1/2
y-intercept= 2 Y X
Down 1 Right 2
BACK
