Let's Review!

True or False?

This is an example of both a function AND a linear function

• True

• False

What is this graph an example of?

• Only a linear function and not a function

• Only a function and not a linear function

• Neither a linear function nor a function

• Both a function and a linear function

What does the b represent?

y = mx + b

• Y - Intercept

• Change in y over change in x

• Where the lines intersect

• Slope

Solve the following: (4,3) (-2,-3)

• y = x - 1

• y = -x + 7

• y = -x + 1

• y = x + 7

The slope intercept formula is...

Solve:

Slope -4 (2,2)

• y = -4x + 10

• y = -4x + 6

• y = -4x - 6

• y = -4x - 10

What does the m stand for?

y = mx + b

• Y - intercept

• Change in y over change in x

• Where the two lines intersect

• Slope
