Answer 1

@hartnn

Answer 2

the y co-ordinate of all the points on a horizontal line is same

so the equation of the horizontal line will be
y= c

where c is the y co-ordinate of any point on the line

Answer 3

in your graph, can you find y co-ordinate of any point on that line?

Answer 4

-4?

Answer 5

yep, so the equation would be y = -4

Answer 6

so thats my final answer yea?

Answer 7

ty

Answer 8

yes :)

Answer 9
