(y-1)/(x+3) = 3/4
4(y-1) = 3(x+3)
4y-4 = 3x+9
3x-4y+13 = 0

Not sure where you want to go with this.

Thank you Steve can you explain what your step are in the problem above you worked for me please.
Answered by Steve
all I did was clear the fractions, just as you would if you were doing, say,

x/2 = 3/7
7x = 3*2

After that, I just expanded terms and simplified. You never said what you wanted to do with the fractions. Naturally, if y=4 and x=1,

(y-1)/(x+3) = 3/4
