Answer is (2, 2)
See graph where the two lines intersect

Step by step

We know x= 2 is a point on the x axis and it’s a vertical line since there is no y value.
Graph this point and line.

y = mx + b is the slope intercept formula
So we know y= 2x - 2 has a point on the y axis of -2 ( the y intercept) and has a slope of 2/1 from that point.

Graph (0, -2) and from there, go up +2 and over right +1. That is your second point. Draw your line.

Now you can see where the two intersect at (2, 2)

Problem solved!

We know there is only 1 solution, since this is two lines intersecting

x=2 is a vertical line

y = 2x-2

Has a y intercept at -2 and a slope of 2

The two lines intersect at x=2, y=2

(2,2)
