Question

How do you graph these two together?

Y=-x+2 
Y=3x-1

nnesha · Answer

just like a simple linear equation 
graph first equation and then the 2nd one

nnesha · Answer

y=mx+b slope intercept form equation where m is slope and b is y-intercept 
so start with y-intercept 
lets say the equation is y=4x+9 
so i draw a point at 9|dw:1449118546021:dw|
and then slope which is rise /run

nnesha · Answer

the slope is 4 in that example 
which is same as $$\rm \frac{ 4 }{ 1 }=\frac{rise}{run}$$
4 =rise 
1= run 
so go up 4 and then 1 to the right |dw:1449118644085:dw|
and then draw a line passes through those two points
