You can put this solution on YOUR website! A line passes through (r,5) and (6,r).
If the slope is five eights what is r equal to?
use the slope formula: m =
In this problem: m=; x1=r, y1=5; x2=6, y2=r
8(r-5) = 5(6-r)
8r - 40 = 30 - 5r
8r + 5r = 30 + 40
13r = 70
r = 5.3846
Check on calc: enter: (5.3846-5)/(6-5.3846) ~ .625 which 5/8
