Question

What is the ordered pairs that satisfy the equation `2x-5y=10`?

Answer 1

As below.

Explanation:

let x = 0. Then y = -2.The ordered pair is a solution to 2x - 5y=10 .
We will add it to the table.

We can find more solutions to the equation by substituting any value of x or any value of y and solving the resulting equation to get another ordered pair that is a solution.

Now we can plot the points on a graph sheet. By joining them we get the required line.
