8.) A line passes through the points (k, 4) and (3, -6). The line is perpendicular to the graph of 5y + 4x = 8. What is the value of k?

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
