Question

find the missing coordinate to complete the ordered pair (3, ) so that satisfies the equation:3x-y=4

Answer 1

(3, ) means x = 3 and y is unknown

Answer 2

Plug in x = 3 and solve for y

3x-y=4

3*3-y=4

9-y = 4

9 = 4+y

9-4 = y

5 = y

y = 5

So the ordered pair, ie point, that is on this line is (3,5)
