Question

Which of the points shown below are on the line given by the equation y = x + 2? Check all that apply.

Answer 1

D

1) To find out which points are on the line y =x+2, we need to plug them into that equation. Like this:

y= x +2

a) Point (1,2) Remember (x, y) so:

y= x +2

2 = 1 +2

2 = 3 FALSE

b) Point B (-1,-2)

y= x +2

-2 = -1 +2

-2 = 1 FALSE

c) Point C (4,2)

y= x +2

2 = 4 +2

2 = 6 FALSE

d) Point D (0,2)

y= x +2

2 = 0 +2

2 = 2 TRUE

2) Hence, the answer is D
