Slope Intercept Form Graph an equation using the slope and the y intercept and write an equation of a line.

Slope and y intercept y = 3/2x - 4 (0, ?) y = 3/2x + 3 (0, ?)

Vocabulary y – intercept : where the line crosses the y axis.
Slope – intercept form: y = mx + b m = slope b = y – intercept

Identify the slope and y - intercept
y = 3x – 2 Y = -2x – 8 M = 3 B = -2 M = -2 B = -8

Graph y = 1/3x + 5

Graph y = 2/3x - 6

Graph y = 2/5x + 1

Graph y = -x - 1

What are the slope and y – intercept of y = x?

Write an equation of the line. Use slope intercept form. Y = mx + b
What is the y – intercept (b)? -2 What is the Slope (m)? 2 y = 2x - 2

Write an equation of the line. Use slope intercept form. Y = mx + b
What is the y – intercept (b)? 3 What is the Slope (m)? 1 y = x + 3

Group Challenge Why is it impossible for any point to lie on both y = 3x + 5 and on y = 3x – 2? Use a graph to illustrate your explanation.

Write an equation of the line. Use slope intercept form. Y = mx + b
What is the y – intercept (b)? 4 What is the Slope (m)? 1/2 y = 1/2x + 4

Group Challenge Explain why it is impossible for any for any point to lie on both y = 3x + 5 and y = 3x -2? Use a graph to illustrate your explanations.
