Question

Give the equation of the horizontal line through the point (3,5)​

Answer 1

y=5 would be the equation

Explanation:

when the line is horizontal you would take the y coordinate of the coordinate given to you and put that into y=n with n being the value of the y coordinate

if the line were vertical you would take the x coordinate of the coordinate given to you and put that into x=n with n being the value of the y coordinate
