Question 1195387
<br>
If the line is horizontal, then the y value is constant (and the value of x doesn't matter).  The equation is<br>
ANSWER: y=2<br>
or, to see that the value of x doesn't matter, you could write the equation as<br>
y = 0x+2<br>
Seeing the equation in that form quickly shows you two things:
(1) The value of x doesn't matter (0 times x is always 0)
(2) The slope of the line is 0, which means it is horizontal<br>
