If y = 2x - 3, then which of the following ordered pairs lies on the graph?
(1, -1), (-3, 0), (5, 4)

Solution:

The equation given is

y = 2x - 3

In order to find if the ordered pairs lies on the graph

We have to substitute the given points in the equation

When (1, -1)

-1 = 2(1) - 3

-1 = 2 - 3

-1 = - 1

When (-3, 0)

0 = 2(-3) - 3

0 = -6 - 3

0 = -9

When (5, 4)

4 = 2(5) - 3

4 = 10 - 3

4 = 7

Therefore, the ordered pair (1, -1) lies on the graph.

If y = 2x - 3, then which of the following ordered pairs lies on the graph?

Summary:

If y = 2x - 3, the ordered pair (1, -1) lies on the graph.
