The equations and features of the lines are, respectively: Horizontal line: y = - 5, Slope: 0, Vertical line: x = 3, Slope: Undefined.
How to define the equations and features of two lines
Herein we find two lines set on Cartesian plane, that is, a horizontal line and a vertical line. Each line is defined according to the following expressions and features:
Horizontal line: (line b)
y = a, Slope: 0
Vertical line: (line a)
x = b, Slope: Undefined.
Then, by direct inspection, we find that the equation and features of the lines are, respectively:
Horizontal line: y = - 5, Slope: 0
Vertical line: x = 3, Slope: Undefined.
