Two eighth-grade classes are selling raffle tickets to raise money.

One class is selling tickets for $2.50 each and has already raised $350.

The other class is selling tickets for $3 and has already raised $225.

Which equation can be used to find t, the number of tickets each class needs to sell so that the total amount raised by each class is the same?

• 3t + 350 = 2.5t + 225

• 350t + 2.5 = 225t + 3

• 2.5t + 350 = 3t + 225

• none of the above

What is the correct equation in 
Slope-Intercept Form?
(y = mx +b)

• y = x + 2

• y = 2x - 1

• y = -x + 2

• y = -2x - 1

The steepness of a line. The m value in y=mx+b.

• slope

• y-intercept

• origin

• equation

Where a line crosses the y-axis. The b value in y=mx+b.

• slope

• y-intercept

• origin

• equation

What does it mean if an equation is written as y=mx

• The line passes through the origin

• The line has a zero slope

• It represents a proportional relationship

• The y-intercept is zero

Is this mapping a function or not a function? 

• Function

• Not a Function

• Function
• Not a Function

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)

• (3,4) (4,-3) (7,4) (3, 8)

• (6,-5) (7, -3) (8, -1) (9, 1)

• (2, -2) (5, 9) (5, -7) (1, 4)

Match each model with the correct equation

• 2 + x = 3x + 4

• -2x - 1 = -3 - 4x

• 2x + 1 = 3 + 4x

• 2 - x = -3x + 4

6x - 1 = 11 + 5x
