Answer: choice D. (5, 28)
====================================================
Explanation:
The idea is to plug in each pair of coordinates and see if you get a true equation. Choice A does not work because
y = 6x-2
20 = 6(6)-2 ... plugged in x = 6 and y = 20
20 = 36-2
20 = 34
we have a false equation. So this shows choice A does not work.
--------
However, choice D does work since...
y = 6x-2
28 = 6(5)-2 .... plug in (x,y) = (5,28)
28 = 30-2
28 = 28
Put another way, if we plugged x = 5 into the equation, then we'd get y = 28. Therefore, showing (5,28) is a point on the line y = 6x-2.
