Question

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


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

Answer 1

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

Plug in the x and y values and simplify to see if the statement is true

(3)=2(0) -3
3 = 0 - 3
3= -3
no

-1 = 2(1) - 3
-1 = 2 - 3
-1 = - 1
yes

4 = 2 (-1) - 3
4 = -2 -3
4 = -5
no

Answer 2

what about this one?

Which of the following points does not lie on the line whose equation is x+ y = 7?


(-10, 17)
(13/3, 8/3)
(-1, -6)

Answer 3

Do the same thing, plug in the x and y values and simplify to see it the statement is true

-10+17 = 7
7 = 7
yes

13/3 + 8/3 = 7
7 = 7
yes

-1 -6 = 7
-7 = 7
no

Answer 4
