Find the equation of the line in slope-intercept form. 

• y = - 1/4x - 3
• y = 1/3x + 3
• y = - 1/4x + 2
• y = 1/3x -3

Which is the graph of y= -x + 2?

• A
• B
• C
• D

Write the equation in slope-intercept form (solve for y):
2y = 10x + 14

• y = 10x + 12
• y = 10x + 7
• y = 5x + 14
• y = 5x + 7

A driving range charges $4 to rent a golf club plus $2.75 for every bucket of golf balls you hit. Write an equation that shows the total cost c of hitting b buckets of golf balls.

• c = 2.75b + 4
• c = 2.75b
• c =  4b- 2.75
• c = 2.75b - 4

Create a scatterplot from this data. Write the line of best fit for the data.

• y = 5.02x + 1.82

• y = 8x - 15

• y = 1.82x +5.02

• y = -1.82x +5.02

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.
