Write the equations of a horizontal line and a vertical line

Write the equations of a horizontal line and a vertical line that pass through the given point. (-15, 4) The horizontal line is y = .

Solution

The equation of a horizontal line is in the form y=k. Since it passes through (-15,4).

Hence, equation of horizontal line is y= 4

Now, equation of a vertical is in the form x=k. Since it passes through (-15,4).

Hence, equation of vertical line is x=-15
