7. Three corners of a rectangle are located at (20, 2), (-10, 2), and (-10, 8). Find the location of the fourth corner. Hint: It may be easiest if you plot the points! A. (2, -10) B. (20, 8) C. (-10, 20) D. None of these. E. (8, 20) 8. A line perpendicular to the x-axis is called a vertical line. 9. If (3, b) is a solution of the equation 3x - 2y = 17, what is b? A. b = 11/3 B. b = 23/3 C. b = 4 D. None of these E. b = -4 10. Choose the coordinates of point F. A. None of these. B. (- 6, 2) C. (-2, 6) D. (6, -2) E. (2, - 6) 11. Slope is Determine the slope and the y-intercept for the linear equation 5x - 2y = 10. Be sure to write the slope as a whole number or a fraction (like 3/2) - not a decimal. Write the y-intercept as an ordered pair - in parentheses and with commas between the coordinates. Slope is 5/2 and y-intercept is (0, -5) . 12. Write the equation of the line with a slope of 3 and a y-intercept of (0, 1) in slope-intercept form. The equation is y=3x+1 13. Determine the slope of a line perpendicular to a line whose slope is 7. A. The slope of a perpendicular line is 7. B. None of these. C. The slope of a perpendicular line is - 7.
D. The slope of a perpendicular line is 1/7.

### 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.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• 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.
