You can put this solution on YOUR website!
y=2x
this is linear equation and the graph is a line
to graph a line we need two points that lie on a line (a line is defined by two points)
first find the x-intercept

y=2x ...set y=0
0=2x
x=0
the x-intercept is at (0 ,0 )

now find one more point

y=2x ...set x=1
y=2%2A1
y=2
the point is at (1 ,2 )

plot these points and draw a line through

The equation is already solved. It shows y equated to an expression with x.
Pick any two or more values for x and evaluate the corresponding values for y.
Now graph your (x,y) points.
