Changes in Slope and Y-Intercept

For the linear equation y = a * x + b, which variable controls the steepness of the graph?

• a

• x

• b

• y

Given the linear function f(x) = (1/2)x+2. What would the effect of the graph be if you multiplied the slope by -4?

• The graph of the line would become steeper, while the slope is still positive.

• The graph of the line would become steeper, but the slope is would be negative.

• The graph of the line would become flatter, while the slope is still positive.

• The graph of the line would become flatter but the slope would now be negative.

Which of the following equations would has the flattest (least steep) slope?

• y = x

• y = -.03x + 4

• y = .5x + 6

• y = -7.2x + 8.5

Identify the line less steep than:

y = 3x + 8

• y = 5x + 8

• y = 3x + 5

• y = -3x + 6

• y = 2x + 7

Choose ALL the equations that have the

same steepness as y = 3/4x + 9

• y = -3/4x - 6

• y = 0.75x + 1

• y = -4/3x + 9

• y = -9/12x - 2

What is the slope in the picture?

• Positive

• Negative

• Zero

• Undefined

What does "m" represent in y=mx+b?

• y-intercept

• slope

• macaroni

• nothing
