Question

Which of the following points lies on the line whose equation is y=2x-3?

(-1,4) (1, -1)
(0,3)

Answer 1

Option B: (1,-1)

Explanation:

To solve these types of questions, you must first draw the graph. Then, you can see which point is on the line.

(I personally use Desmos's Graphing Calculator for the graph. Just put the equation in, and the line is drawn for you!)

I hope this helps!

Answer 2

(1, -1)

Explanation:

y - (-1) = 2 (x - 1)

y + 1 = 2x - 2

y = 2x - 2 - 1

y = 2x - 3
