Answer:
y = 8
Step-by-step explanation:
x = 11 is a vertical line (straight up and down). All equations of the form
x = anumber
are vertical lines.
Perpendicular lines make right angles, "square corners", 90° like a wall and the floor!
So the line perpendicular to a vertical line is a horizontal line(like the horizon, a left and right, completely flat line)
A horizontal line has the form
y = anumber
in this case you have a point (x, y), that is given (1, 8) so what does y equal?
y = 8
