Melissa is trying to save money to buy some new DVDs.

-Melissa has already save $20.

-She gets a part-time job after school making $8.15 an hour.

-Melissa decides to save everything she makes.

Which linear equation represents how much money Melissa will save after working x hours?

• y = 20(8.15) + x

• y = 20x + 8.15

• y = 8.15x + 20

• y = x + 20 + 8.15

Which equation represents the line that passes through the points (-3, 2) and (6, -1) ?

• $y\ =\ -3x\ +\ 12$

• $y\ =\ -3x\ -\ 3$

• $y\ =\ -\frac{1}{3}x\ -\ 1$

• $y\ =\ -\frac{1}{3}x\ +\ 1$

Which equation best represents line a ?

• $y\ =\ -\frac{2}{3}x\ -4$

• $y\ =\ -\frac{2}{3}x\ +\ 4$

• $y\ =\ \frac{2}{3}x\ -\ 4$

• $y\ =\ \frac{2}{3}x\ +\ 4$

Which is the equation for the line that passes through (-4,0) and has a slope of -3?

• y = -3x - 4

• y = -3x

• y = -3x - 12

• y = 3x - 4
