When you have

you can solve the equation by multiplying both sides by 1/4. Then simplify.

Put 3x + 3y = 45 in slope intercept form
y = 15 - 3/3x
(-3/3x is just going to simplify to -1x though)
Perpendicular form of -1x would be 1x
So your perpendicular slope would be 1
7/2x is ur answer since the denominator is the same so you just add the numerators together
Answer:
15/5 or 3
