Find an equation for the horizontal line through the point (2,−8).

X=2

Step-by-step explanation:

X is the horizontal line and in this coordinate pair, 2 is our X. Therefore X=2

y = -8

Step-by-step explanation:

You can have a horizontal line parallel to the x-axis which is also known as y=c. Since you had the point (2,-8) you can simply write y = -8 as an equation.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
