The points (-11, r) and (-6, 12) lie on a line with slope 2. Find the missing coordinater r.

r=2

Step-by-step explanation:

We can use the given 2 points to find slope. Since we are given the slope, we can plug it into the formula and solve for r.

                                       [plug in values]

                                  [combine like terms]

                                         [multiply both sides by 5]

                                     [subtract both sides by 12]

                                         [divide both sides by -1]
