On the line having the equation y = 2x - 8
-8 = 2(0) -8 = 0 - 8 so (0, -8) is a coordinate
0 = 2(4) - 8 = 8 - 8 so (4, 0) is also a coordinate

All you have to do to answer this question is plug the numbers into the equation. In each set, the first number is the value of x and the second is the value of y. So, with the equation y = 2x - 8
(0, -8) yields -8 = 2*0 - 8 = -8
(4, 0) yields 0 = 2*4 - 8 = 0
Both are points on the line described by the equations.

Since both are, one could be.
-8 = 2*0 - 8
0 = 2*4 - 8

yes when inputted into the equation: -8=0-8 and 0=8-8

Yes.
y=2x-8
when x=0 then
y=2(0)-8
y=-8
the ordered pair is (0,-8)
when x=4
y=2(4)-8
y=8-8
y=0
the ordered pair is (4,0)

You are absolutely correct.
The two co-ordinates (0,-8) and (4,0) are answers to y= 2x-8

x = 0
y = 2x - 8
y = 2(0) - 8
y = 0 - 8
y = - 8
The ordered pair (0, - 8) is correct
- - - - - - - - - - - - - - -
x = 4
y = 2x - 8
y = 2(4) - 8
y = 8 - 8
y = 0
The ordered pair (4, 0) is correct
