Find x such that the line through (6, −3) and (7, 6) is perpendicular to the line through (−2, 5) and (x, −1).

Question

Find x such that the line through (6, −3) and (7, 6) is perpendicular to the line through (−2, 5) and (x, −1).

Answer 1

Determine slope between (6, -3) and (7, 6)

Take the negative reciprocal of that slope

Use the negative reciprocal as the slope of the line through

(-2, 5) and (x, -1)
