Cherries cost $4 /lb. Grapes cost $1.50/lb You can spend no more than $9 on fruit, and you need at least 3 lb in all. Write the equation (s) in slope intercept form

1.5y = - 4.5x+9 or y = - 3x+6

and y = - x+3

Step-by-step explanation:

First, you need to make a system of linear equations.

x=pounds for cherries

y=pounds for grapes

This would be:

4x+1.5y=9

x+y=3

Then, change the equations into slope intercept form.
