How do you solve linear equations

Y=mx+b if you mean graphing

m=rise/run or slope

b=your y intercept in linear equations they have them or you rearrange/get the y (which is at the start of the problem) alone. then you graph like say ...

y=2x+1

you would rise 2 and go right 1 and you start on 1 on the y intercept of graph
