Chapter 3: Graphing Linear Functions

What is a linear function?

• A straight line

• A curved line

• y = 5x

• y = 8/x + 7

What is the formula for linear function?

• y=mx-b

• y=x+b

• b=mx+y

• y=mx+b

y=mx+b - which one is the y-intercept?

• y

• b

• m

• x

y=mx+b - which one is the slope?

• y

• x

• m

• b
