Question

What is the equation of the line perpendicularto y = 1/2x + 6 that passes through the point(4, 1)?

Answer 1

Two lines are perpendicular when their slopes are opposite.

You have the equation;

`y=(1)/(2)x+6`

You can identify the slope as the number next to the x (y=mx+b, m is the slope)

the slope in the given equation is 1/2

The slope of the perpendicular line will be the opposite
