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

Jenny writes the equation y = 1/2x +5.
Why is she incorrect?

The slope is -2, the equation should be
y = -2x + 5

The y-intercept is 4, the equation should be y = -2x + 4

The slope is -1/2, the equation should be
 y = -1/2x + 5

The y-intercept is -5, the equation should be y = -2x - 5
