The points (-2, 8) and (r, − 1) lie on a line with slope -3. Find the missing coordinate r.


ILL GIVE BRAINLIEST TO WHOEVER HELPS ME QUICKLY AND CORRECTLY!



Answer :

Answer:
r = 1

:The x-coordinate of the partially-defined point is 3 units less than the x-coordinate of the given point. The slope of 2 tells you the y-coordinate of the partial point (r) will be 2·3 = 6 units less than the y-coordinate of the given point. That is r = 1 - 2·3  r = -5
