2(x,y) 5
Solution
Here are four steps to walk you through the problem First: you must get the equation to say
y=mx+b 2(x-y)=5 ---------[distribute] 2x-2y=5 --------- [subtract 2x] -2y= -2x+5 -------[divide by
-2 .... BE CAREFUL when you do this, you have to FLIP the sign because you are dividing by a
negative y= x -- (5/2) Second: Get 2 points If you know how to graph the line y= x -- (5/2) do so,
if not I will walk you through it you have to get (at least) two points ....if you have a calculator
you can plug it into y= and then look at the table for some good points .... if you don't have a
calculator plug in an x value to get a y value to have a point Two points: ( 0, -5/2) and (1/2, -2)
Third: make sure you have the correct line if the line is either = or = the line must be SOLID <---
----for you if the line is either < ir > the line must be DOTTED Forth: shade y= x -- (5/2) is the
line we are going to shade since it says = that means everything LESS so you need to put your
pen on a point and draw a line down. Now you know where to shade .... everywhere below the
solid line.
