Bill and ted decided that they wanted to race down the steepest hill. when they compared the slopes of the two hill's they found that beacon hill has a slope of 3x+2y=7 and crabtree hill had a slope of 3y-5x=9. bill and ted figure out which hill has the steepest slope explain to bill and ted which hill they should race down

First, you have to re-order the equations into slope intercept form--
y=mx+b
3x+2y=7
2y=3x+7
y=3/2x+7/2

3y-5x=9
3y=-5x+9
y=-5/3x+9

In the slope intercept form, y=mx+b, m is the variable indicating slope. In this case, Crabtree Hill is steeper, since 5/3 equals 1.66667, while 3/2 equals 1.5. The larger the number, the steeper the slope.
