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.

step-by-step explanation:

2*5=10

4*15=60

60+10=
