Slope Intercept Review

In order to join an online learning community, there is a $20 startup fee and a $5 monthly fee. Write an equation in slope-intercept form that models this situation.

• y = 20x + 5

• y = 5x +20

• y=-5x + 20

• y = 5x - 20

Suppose that a bike rents for $4 plus $1.50 per hour. Write an equation in slope-intercept form that models this situation.

• y = 4x + 1.50

• y = 1.50x + 4

• y = -4x +1.50

• y = 4x - 1.50

An airplane 30,000 feet above the ground begins descending at a rate of 2,000 feet per minute. Write an equation to model the situation.

• y = - 2,000x + 30,000

• y = - 2,000x - 30,000

• y = 30,000x + 2,000

• y = -30,000x + 2,000

What is the y-intercept

• (2,0)
• (0,2)
• (0,-2)
• there is no y-intercept

Select all that apply: In the $y=mx+b$  equation, the m tells us...

• the slope of the line

• the y-intercept of the line.

• where the line crosses the y-axis.

• the rate of change of the line.

• the  $\frac{rise}{run}$   of the line.
