Question

Write an equation for the horizontal line that contains point E(6, –6).
a. x=6 b. x=-6 c. y=-6 d. y=6

Answer 1

when x = 6, y = -6
when y = -6, x = 6
therefore,
y = x -12

Answer 2

lets try when x = 6:
y = (6) -12
y= -6
as in point E (6, -6)

when y = -6:
-6 = x -12
-x = 6 -12
-x = -12
x = 6
as in point E
