Lesson- Finding Slope of a Line

3. Write a number line that shows the solution to the
Warm Up
Linda has $26. She earns $6 for 1 hour (h) of babysitting. She wants to buy a ski pass for $80.
Write an inequality that shows the number of hours (h) Linda could babysit to be able to buy the ski pass.
Write a number line that shows the solution to the
inequality –1 < x?

4. Warm Up Answer Key 1. 2.

5. The dependent variable The independent variable
Define all the parts of the equation.
y = mx + b
Y- intercept
The dependent variable
The independent variable
Slope

6. How do you find the slope from…a graph?
Rise (vertical change)
Run (horizontal change)
a table?
As x goes up by 1, what happens to y?
Find the y ÷ x
an equation?
The coefficient
(the number next to the variable)

7. How can you find the y-intercept and the slope of a line from a:
Question
How can you find the y-intercept and the slope of a line from a:
Line from data
a graph
table Or
an equation?

11. y-intercept = 3 Slope = m = 3 equation: y = 3x + 3
Also, find the y-intercept and write an equation that represents the table below.
y-intercept = 3
Slope = m = 3
equation: y = 3x + 3

12. y = 3x + 6 6 y = 6 - 3x Page 92 1 6 Y-intercept = Slope = Rise = Run
3 or 3 1
-3 or -3 1
Slope = Rise =
Run
Slope = Rise =
Run
y = 6 - 3x
y = 3x + 6

13. Page 92 y = 3/2x – 1 -1 5 Y-intercept = Y-intercept = y = -1/2x + 5 3
Slope = Rise = change in Y =
Run change in X
Y-intercept = -1
y = 3/2x – 1
Y-intercept = 5
-1/2 1
Slope = Rise = change in Y =
Run change in X 5
y = -1/2x + 5

14. Change slope into an improper fraction20
y-intercept = 5
y-intercept =
Slope = coefficient of x
Slope =
Slope = coefficient of x
Slope =
2.5 or 5/2 -3

15. -1 Graph the points? Make a table?
Slope = Rise = change in Y =
Run change in X
Graph the points?
Or calculate the change in y divided by the change in x
(4, 4)
(5, 3)
(6, 2)
Use the table to find 2 more points?
Find the y-intercept , write the equation, use substitution?
