Question

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

zepdrix · Answer

A horizontal line has `zero slope`.
It doesn't rise at all. Only run.

So we're looking for an equation of this form:$$\large\rm y=0x+b$$Or simply$$\large\rm y=b$$Which passes through the point (2,10).

So plug in your point, 10 for the y, 2 for the x (if there is one),
and solve for b.

HI!!

misty1212 · Answer

a horizontal line looks like $y=\text{some number}$
what is that number in this case?

misty1212 · Answer

in other words, what is the $y$ in the ordered pair $ (2, 10)$?

princesssleelee · Answer

10
