Question

Select the coordinates of two points on the line y = 8. A) (8, 8) and (8, 0). B) (8, -8) and (8, 8). C) (0, 8) and (8, 0). D) (0, 8) and (8, 8)

Answer 1

For the line y=8, the gradient is zero;
As such, the line can take any values of x but value of y should remain a constant 8.
The best answer then is D) (0,8) and (8,8)

Answer 2

The given equation of the line, y = 8, is very independent of the value of x. This means that it will take any value for x while y will also be 8. The answer to the question above is letter D. (0, 8) and (8, 8).
