How would you graph y equals 4 and 2x y equals 2?

Answer 1

The first expression, y = 4, would be a horizontal line at y = 4.

The second expression can be found by setting y equal to zero and solving for x, and, likewise, setting x equal to zero and solving for y:

2x = 2 <=> x = 1, so coordinate is (1,0)

y = 2, so coordinate is (0, 2)

Now draw a line connecting those two points and beyond them.
