What is the equation of a horizontal line passing through the point (2,10)
y=12
x=-8
y=10
x=2

y = 10

Step-by-step explanation:

Since it's a horizontal line, the value of y remains constant whatever happens to x, to maintain the fact that it is parallel to the x axis.

So the value of y in the point given is the constant value of y, i.e. y is always 10.

So the equation of the line is y = 10
