Answer:

A. (-2, 6)

Step-by-step explanation:

To put the equation of this line in slope intercept form;

1/2y = -x + 1

Multiplying by 2 on both sides gives;

y = -2x + 2

Checking option (A);

6 = -2(-2) + 2

6 = 4 + 2 = 6

∴ This option is a solution.

Checking option (B);

2 = -2(-6) + 2

2 ≠ 14

∴ This option is not a solution.

Checking option (C);

-6 = -2(-2) + 2

-6 ≠ 6

∴ This option is not a solution.

Checking option (D);

-6 = -2(2) + 2

-6 ≠ -2

∴ This option is not a solution.
