Question

Determine whether the ordered pair (0, 2) is a solution to the equation –2x + y = –1.

Answer 1

Below.

Explanation:

The ordered pair (0, 2) tells us that x = 0 when y = 2.

We just plug these values in the given equation and see if the left side = the right.

Left side = -2(0) + 2 = 2.

Right side = -1.

- so they are not a solution.
