You can put this solution on YOUR website! This is something of a trick question.
y = 5 does not have an 'x' term. So regardless of the value of x, y=5.
This is a horizontal line that passes through (0,5).
It is parallel to the x-axis, so it does not have an x-intercept.
.
So, a horizontal line that passes through (1,2) would be y=2.

.
Done.
