Answer:
- horizontal: y = 3
- vertical: x = 2
Step-by-step explanation:
You want the equations of the horizontal and vertical lines that pass through (2, 3).
Horizontal line
A horizontal line has an equation of the form ...
y = c . . . . . for some constant c
The value of y is the same for every value of x.
To make such a line go through the point (2, 3), we must have ...
y = 3
Vertical line
A vertical line has an equation of the form ...
x = c . . . . . for some constant c
The value of x is the same for every value of y.
To make such a line go through the point (2, 3), we must have ...
x = 2
