Question

Choose the equation of the horizontal line that passes through the point (-8, -7).

y = -8

y = -7

x = -8

x = -7

Answer 1

horizontal line will be of form :-

\(y = k\)

Answer 2

I know right away I have to elimate the x values.

Answer 3

all points on horizontal line, will have same y-coordinate : \(k\)

Answer 4

Because they are vertical

Answer 5

eliminate*

Answer 6

whats the y-coordinate of GIVEN point ?

Answer 7

(-8, -7)

Answer 8

-7

Answer 9

So B?

Answer 10

y = -7

since all points must have same y-coordinate.

Answer 11

Yup ! you have really good eyes... when figuring that out :)

Answer 12

Haha thank you!

Answer 13

horizontal lines have same distance from x axis and distance from x axis is given by y-co-ordinate :)
