Linear Equations in Two Variables

Find four solutions for each question and graph the equation.
y=2x3

The answer to this question is any point (x,y) which lies on the lien.
To find points that lie on the line, substitute any finite value of x, and evaluate y. Present the answer as a coordinate pair (x,y).
For example,
let x=1, y=2x3=2(1)3=1
So (1,1) is a point on the line (a solution to the linear equation). 
y=2x3
When x=0
y=2(0)3
y=03
y= 3
When x=1
y=2(1)3
y=23
y= 1
When x=2
y=2(2)3
y=43
y= 3
When x=3
y=2(3)3
y= 63
y=3
The four solutions are:
(0,3) (1,1) (2,3) (3,3)
As the solutions have been found draw a graph and plot them.
