Answer:

a, b & d

Explanation:

y - 10 = 2x

Divide by 2

½y - 5 = x

½y = x + 5

Basically both equations represent the same line, so infinite solutions

(0,10) is a solution

10 - 10 = 2(0)

0 = 0

(1,12) is a solution

12 - 10 = 2(1)

2 =

(2,-6) is not a solution

-6 - 10 = 2(2)

-16 = 4

(-5,0) is a solution

0 - 10 = 2(-5)

-10 = -10

Answer:

A, B, and D

Explanation:

Let's put all the answer choices in for x and y in both equations:

A) x = 0, y = 10

10 - 10 = 2 * 0 --> 0 = 0, which works

1/2 * 10 = 0 + 5 --> 5 = 5, which works

So, A is correct

B) x = 1, y = 12

12 - 10 = 2 * 1 --> 2 = 2 which works

1/2 * 12 = 1 + 5 --> 6 = 6, which works

So, B is correct

C) x = 2, y = -6

-6 - 10 = 2 * 2 --> -16 = 4, which doesn't work

So, C is incorrect

D) x = -5, y = 0

0 - 10 = 2 * -5 --> -10 = -10, which works

1/2 * 0 = -5 + 5 --> 0 = 0, which works

So, D is correct

Thus, the answers are A, B, and D.

Hope this helps!
