solve x=-2y? I will then need to graph it.
---------------
Divide both sides by -2 to get:
y = -(1/2)x
-----------------
Plot 2 points and draw a line thru them:
If x = 0, y = 0
If x = 2, y = -(1/2)*2 = -1
------------
Plot the points (0,0) and (2,-1)
------------

x = -2y
This is a linear function.
All you need is two points to graph it.
Linear functions make straight lines. The word linear means line.
There are many ways to find points.
Let x = 0
0 = -2y
0/-2 = y
0 = y
One point to graph is (0,0). This particular point is called the origin.
It's where the x and y axis meet.
Solving for y, we get the equation y = x/-2.
If we let x = 2, y = -1.
This makes the point (0, -1).
Plot these two points on the xy-plane and connect the points with a straight line going from quadrant 2 down through the origin into quadrant 4.
