Question

Find an equation of the line perpendicular to y = 4 and passing through (1, 5)

y=mx+b

I’m not sure.

Answer 1

Answer:

x=1

Step-by-step explanation:

y=4 is a horizontal line, and we know that vertical lines are perpendicular to horizontal lines, so the answer has to be a vertical line.

Vertical lines do not have a slope, instead the equation is always x=a, a being the point on the x axis the line intersects it.

Since the x of (1,5) is 1, then x must equal 1.

The answer is x=1
