y=-1/4x +4

y=7/4x -4

**Reiny**, Friday, August 23, 2013 at 8:20ameach is a straight line, so pick any two points for each line

In this case, pick multiples of 4 for your x choice to avoid fractions

e.g. let x = 4, then y = 3 ---> (4,3)

let x = 8, then y = 2 ----> (8,2)

for the 2nd,

let x = 4, then y = 3 ---> (4,3)

let x = 8, then y = 10 ---> (8,10)

your graph should look like this:

looks like the solution is (4,3), (which I just happened to have chosen by sheer luck)

I just added a domain of 0<x<10 to take a closer look
