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) 

Steve started with $250 and spent $25 per week. Chelsea started with $30 and saved $30 per week.

Which two equations represent these situations?

• y = 250 - 25x

• y = 30 + 30x

• y = 250x + 25

• y = 30x - 30
