Question

Points C(5, 7) and D(–3, –12) are on a line. What is the run from point D to point C?

 

  1. a. -8
  2. b. -5
  3. c. 8
  4. d. 19

hintHint:

Run from 1 point to another can be found by calculating the difference between x-coordinates of the 2 points i.e. Run = x2 - x1.

The correct answer is: c. 8


    GIVEN-
    Point C (5,7)
    Point D (-3,-12)
    TO FIND-
    Run from point D to point C.
    SOLUTION-
    For points D (-3,-12) and C (5,7), x1 = -3, y1 = -12, x2 = 5 & y2 = 7.
    Run = x2 - x1
    ∴ Run = 5 - (-3)
    ∴ Run = 5 + 3
    ∴ Run = 8
    FINAL ANSWER-
    Option 'c' i.e. '8' is the correct answer to the given question.
