Question

What is the equation of a horizontal line passing through (–5, 3)?

x = –5

y = –5

x = 3

y = 3

Answer 1

Hint: All horizontal lines have points on them where the y coordinates of each point are the same

Answer 2

i was thinking -3

Answer 3

what is the y coordinate of the given point?

Answer 4

3...

Answer 5

so all points on this line must have a y coordinate of 3

Answer 6

ie...y = 3

Answer 7

ok.. so y = 3

Answer 8

yep

Answer 9

points like (1,3), (55,3) and (-18,3) all lie on this line

so does (-5,3)

Answer 10

as long as the y coordinate is 3, the point will lie on the horizontal line y = 3
