WRITE AN EQUATION
You bought a $5 magazine and four
erasers. You spent a total of $25. How
much did each eraser cost?

• 5+x=25

• 5+4x=25

• 5x=25

• 23-5=4x

Which equation matches the function described in the table?

• y = x – 4

• y = 4x – 1

• y = -4x + 1

• y = -3x – 2

Determine the slope and y-intercept from the following equation: y = 3/2x + 3

• slope: 5 y-intercept: (0,3)

• slope: 3/2 y-intercept: (0,3)

• slope: 4 y-intercept: (0,3/2)

• slope: 1/5 y-intercept: (0,5)

Solve:
7x - 3x - 8 = 24

• 8

• -8

• 3.2

• 4

Solve for x:
8x + 2 + 3x + 5 = x + 12

• -1/2

• 2

• -2

• 1/2

Solve for x:
2(3x + 4) + 2 = 4 + 3x

• 2

• -2/3

• 10

• -2

MGSE8.F.2, MGSE8.EE.5, MGSE8.F.3: A reporter collected data on y, the depreciation of a certain car for various years, x, after it had been purchased new. The equation below was fit to the data. y = 16,500 -1,500x What is the rate of change (slope) in the above equation?

• A. 16,500

• B. 1,500x

• C. -1,500

• D. -1,500x

What is the equation of this line?

• y= 3x+1

• y= -x+3

• y= 1/3x-1

• y= -1/3x+1

Change the following equation to slope-intercept form:

5x - 5y = 25

• y = x - 5

• y = 5x - 1

• y = -x + 5

• y = 5x + 1

How many solutions are there?
4x-1=4x-1

• one solution 

• many solutions

• no solutions
