Algebra – Distance between Points True/False Questions and Solutions Questions: 1. (True or False) The distance between the numbers -9 and 20 is equal to the distance between 9 and -20 on the number line. 2. (True or False) If f(x) = sqrt(1 - x), then f(-3) = 2. 3. (True or False) The slope of the line 2x + 2y = 2 is equal to 2. 4. (True or False) |x + 5| is always positive. 5. (True or False) The distance between the points (0 , 0) and (5 , 0) in a rectangular system of axes is 5.

    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.
