A camp charges families a fee of $625 per month for one child and a certain amount more per month for each additional child. Use the graph to write an equation in slope-intercept form to represent the amount a family with x additional children would pay.

• y = 625x + 225

• y = 225x 

• y = 225x + 625

• y =  625

You are visiting Baltimore, MD and a taxi company charges you a flat fee of $3.00 for using the taxi and $0.75 per mile. Which of the following equations matches the situation?

• 0.75x + 3y = 50

• y = 0.75x + 3

• y = 3x + 0.75

• 3x + 0.75y = 50

• 50 = -0.75x + y

Find the slope-intercept equation

• y = 2x + 3

• y = -2x +3

• y = ¹/₂ x+3

• ^{y = -1}/₂ x+3

Find the slope-intercept equation

• y = 3x + 5

• y = -3x + 5

• y = ^-1/₃ x + 5

• y = ^-1/₃ x - 5
