1. write an equation of a line perpendicular to line ab below in slope-intercept form that passes through the point (7, 6).

line ab is shown. a is at 0, 1. b is at negative 2, 5.

y = 0.5x + 2.5

y = 0.5x − 2.5

y = −2x + 20

y = 2x − 20

2. write an equation of a line perpendicular to y = 1 over 4x + 4 in slope-intercept form that passes through the point (−2, 6).

y= 1/4x − 4

y= 1/4x + 6

y= −4x − 2

y= −4x + 1/4
