Question 239341: how do you graph y=x
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! You plot some selected points for x and then calculate the y value and then plot the points on the graph and then draw a straight line through the points.
Example:
When x = 0, y = 0
When x = 10, y = 10
Plot (x,y) = (0,0) on the graph.
Plot (x,y) = (10,10) on the graph.
Draw a straight line between them.
There's your graph.
The point (x,y) is x units to the right or left of x = 0, and y units up or down from y = 0.
If x is negative, you move to the left.
If y is negative, you move down.
If x is positive, you move to the right.
If y is positive, you move up.
A graph of your equation looks like:
