Question

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

Answer 1

In which form? Standard? Slope-intercept?

Answer 2

standard form

Answer 3

y = 12

x = −8

y = 10

x = 2

Answer 4

those are the answer choices, but i dont understand how to do it

Answer 5

We know that all horizontal lines have a slope of 0, so we can find our answer from there!
We will start with the point-slope form on an equation.
y-10 = 0 (x-2)
Then we multiply.... y-10=0. Subtract y=10.
Standard form is ax+by=c (btw)
Because the line is horizontal you really do not have to go through all these steps, if you were to graph it, you would see that the x-coordinates do not really matter when it comes to answering this question.
Anywho, the answer is y=10
:) Hope this helps!

ahhh, thanks! that helped alot for me to understand it better now, thanks again :)
