Question

What is the equation of a horizontal line passing through the point (2, 10)?

y = 12
x = −8
y = 10
x = 2

Answer 1

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).

Answer 2

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

Answer 3

I dont quite understand @zepdrix

Answer 4

HI!!

Answer 5

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

Answer 6

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

Answer 7

10

Answer 8

yes

Answer 9

y=10! WOW! Thank you! lol
