The points (3,13) and (r,-7) lie on a line with slope -5 . Find the missing coordinate r.
Added by Stephen R.
Step 1
The slope formula is given by: m = (y2 - y1) / (x2 - x1) where (x1, y1) = (3, 13) and (x2, y2) = (r, -7). Substituting the values into the formula, we get: -5 = (-7 - 13) / (r - 3) Show more…
