Question 1140108: if point A, having coordinates (9,p) and point B, have coordinates (p,7), lie on a line having slope of -1/3, what is the value of p?
Answer by MathLover1(20849) (Show Source): You can put this solution on YOUR website!
given:
point =(,)
point =(,)

use slope formula:
.......plug in coordinates of given points
...........solve or

point =(,)
point =(,)
now, if you want to check solution, use slope point formula to find equation of that line
.......plug in slope and one point

check the solution on a graph:
