Question

How do you graph the inequality `x-4y>8`?

Answer 1

graph{x-4y>8 [-10, 10, -5, 5]}

Explanation:

The above graph is the solution for `x-4y>8`
It can be obtained by the following method.
First let x = 0, then `y<-2`.
So now we mark the point (0,-2)
We do a similar process with y=0 and get the point (8,0)
We then join the two lines and the solutions for the inequality is the region under the line (not on the line).
