You can put this solution on YOUR website! write the equation of the line passing through point (-2,4) and parallel to the x-axis.
-----
1st: plot the point
2nd: draw the line thru the point parallel to the x-axis
---
3rd: Notice that the line passes thru all the points
where y = 4.
----
Equation:
y = 4
