Question

Which step is included in the construction of perpendicular lines using a point on the line?

Answer 1

You need to have 2 points to form a line, therefore a slope.

If slope = m

Then -1/m will be the slope of the perpendicular line.

So you would need to take a second point on the line, determine the slope using the first point, say A, and the second point, say B by the following method.

A(x1, y1)
B(x2, y2)

m = [y2-y1]/[x2-x1]

Answer 2

Once you have m, you take the opposite reciprocal of it.

Opposite of m is -m
Reciprocal of m is 1/m

Opp Reciprocal of m = -1/m

Answer 3

Does this make sense bud?
