Linear Function from Graph

The graph models the value of a machine over a 10 year period. Which equation best represents the relationship between x, the age of the machine in years, and y, the value of the machine in dollars over this 10 year period?

• y = -0.002x + 2,500

• y = -500x +8,000

• y = 500x +8,000

• y = 0.002x + 2,500

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
