The x coordinate is 2. The y coordinate is unknown.

If we substitute 2 for x in the equation, it will look as follows:
[tex]4 (2)-5y=-12[/tex]

Then we simply have to work it out:
[tex]8-5y=-12 \\ -5y=-20 \\ 5y=20 \\ y= \frac{20}{5} \\ y=4 [/tex]

So, the second coordinate is 4.

Answer: y=4.

Explanation: To find a missing half of a coordinate of a point that belongs to a line, we just have to substitute the known coordinate in the equation of the line, and isolate the variable we are looking for. So in the given problem, we just substitute "x=2" and then isolate "y":

4(2)-5y=-12

8-5y=-12

-5y=-12-8

-5y=-20

y=-20/-5

y=4.

So the coordinate would be (2, 4).
