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

is it x=2 ?? im not sure

Answer 2

Horizontal line means it's (0,0)

Answer 3

so its x=2 ?? yes

Answer 4

So just plug in (0, 0)

to get a slope: \(\LARGE \frac{ 10-0}{2-0} \) gives use what?

And nope

Answer 5

Whoops, mess up there, one sec

Answer 6

5

Answer 7

????

Answer 8

to look at it is that a horizontal line has a slope of zero, so using the point-slope form of the straight line

Answer 9

and in horizontal the slope is always zero
do you got it @itsmichelle29

Answer 10

so y=10

Answer 11

and can it not be x=2

Answer 12

because
as we apply here point slope form
y-y1=m(x-x1)
y-10=0(x-2)
y-10=0
and then
y=10

Answer 13

Yes, the slope is zero, but the coordinates are not always (0, 0), that's where I messed up, sorry.

Since it's (2, 10) and it's passing through it, being horizontal it'll be ( 0, 10)

Answer 14

ohh lol okay i get it now thanks

Answer 15

its y=10

Answer 16

this question is good @itsmichelle29 and interesting one
