Rewrite the equation so that y is a function of x:

1. 1/2(y+5)+4x=3x

2. Use the result in Ex. 1 to find y when x= -1, 0, and 2
__________

Can you please check if this is right?

1. y=-2x+4.5

2. f(-1)=-2(-1)+4.5
=6.5
f(0)=-2(0)+4.5
=4.5
f(2)=-2(2)+4.5
=0.5

Thanks!

1. should be y=-2x-5, check my work.

2. Need to re-do with the new formula.
