Tabitha is trying to find the equation of a line perpendicular to y = 1 over 2x − 5 in slope-intercept form that passes through the point (2, −7). Which of the following equations will she use?

Answer 1

a) y − (−7) = 1 over 2(x − 2)
b) y − 2 = 1 over 2(x − (−7))
c) y − (−7) = −2(x − 2)
d) y − 2 = −2(x − (−7))

Answer 2

First find the slope of the line. You are given the slope of the perpendicular line.

Answer 3

To get the slope of the line, you take the negative reciprocal of the perpendicular slope.
