Question

Which of the following coordinates exists on the line y = 2x - 4?

Answer 1

(0,-4) (1,-2) (2,0) are coordinate points of the line y=2x-4.

Answer 2

(0, -4), (1, -2) and (2, 0)

Explanation:

To find the coordinates, substitute values in for x.

To find the value of y when the x-coordinate is 0,

y = 2(0) - 4 = 0-4 = -4

To find the value of y when the x-coordinate is 1,

y = 2(1) - 4 = 2-4 = -2

To find the value of y when the x-coordinate is 2,

y = 2(2) - 4 = 4-4 = 0
