Question 13 of 25 4.0/ 4.0 Points Find the equation of a line passing through the point (6, 8) and perpendicular to the line y = - 2. A. None of these. B. x = 8 C. y = 6 D. y = 8 E. x = 6 Feedback: Correct. You have chosen the vertical line passing through the point. Question 14 of 25 4.0/ 4.0 Points Find f(-15) when f(x) = - 5x + 30 A. 45 B. None of these. C. - 45 D. 105 E. 105 Question 15 of 25 4.0/ 4.0 Points Write the equation of the line with slope = 2 and containing the point (8, 7). A. y - 7 = x - 8 B. y = 2x + 9 C. y = 2x - 9 Feedback: Correct! Since you were given the slope and a point, you used the point-slope equation of a line to find the answer. D. y - 7 = mx - 8 E. None of these Question 16 of 25 4.0/ 4.0 Points Write the equation of the line passing through the points (4, 12) and (4, - 8).

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
