Question 72725
<pre>

how do you solve y=2x

The graph looks like this:

{{{graph (200, 200, -4, 6, -5, 7, 2x)}}}


Assume values of x and substitute it to y = 2x to find the value of y

    x            y
    -2           -4
     0           0
     1           2

Plot the points (-2, -4), (0, 0), and (1, 2)
Draw a line passing the three points.
