The graph of the equation y=x is fairly easy and simple to graph.
- First you need to draw a X & Y coordinate plane..
Draw two perpendicular lines that intersect each other.
Label the vertical one "y"
Label the horizontal one "x"
The point where the two lines intersect is called the origin and also has the coordinates (0,0)
Now number the x-axis and y-axis with equal intervals (recommend intervals on 1, such as: --4,-3,-2,-1,0,1,2,3,4,5,6)
The side right of the origin is the positive x-axis and the left is the negative x-axis.
The top is the positive y-axis and the bottom is the negative y-axis.
- Second: Plot the graph now that you have you coordinate plane drawn
Since it is a y = x graph, all x and y values will be same.
So, easiest is to take any three points and graph them on the plane.
For instance, (-1,-1) , (0,0) , (1,1)
And then draw a straight line that goes through them.
All points along that line are solutions to y=x.
-Third: How should it look?
- It should look like you bisected or went through the middle of a 90 degree angle and it also should be a straight line.
That is how you graph y=x. Hope that helps :)
