Question 206274: Given: P1 (R,R-1)& P2(R+1, 2R-3), Find the slope. (Hint R is a Number).
Answer by mickclns(59) (Show Source): You can put this solution on YOUR website!
slope m is rise / run or difference in y / difference in x
m = ( (2r-3) - (r-1) ) / ( (r+1) - r )
= ( 2r - 3 - r + 1 ) / (r + 1 - r)
= (r-2) / 1 = r-2
In other words, whatever number r is, the slope is 2 less than that.
