Question

Which point is on the graph of the equation y = 2x - 5?

(3, -1)

(2, -5)

(4, 2)

(2, -1)

Answer 1

If you plug in the ordered pairs, the numbers have to be the same on both sides in order to know the answer.
y = 2x -5
-1 = 2(2)-5
-1 = 4 - 5
-1 = -1
The answer is (2,-1)

Answer 2

The answer would be, (2,-1).
