A line contains the points (-2,-6) and (4, 1). Using point-slope form, write the equation of the line that is perpendicular to the given line and that passes through the point (4, 1).
A y-4 = -6/7 (x-1)

Acable company claims that the average household pays $78 a month for a basic cable plan, but it could differ by as much as $20. write an absolute value inequality to determine the range of basic cable plan costs with this cable company. a. |x − 78| ≥ 20 b. |x − 20| ≥ 78 c. |x − 20| ≤ 78 d. |x − 78| ≤ 20
