If the slope is five eights what is r equal to?Answer by ankor@dixie-net.com(15647)   (Show Source): 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 : = Cross multiply 8(r-5) = 5(6-r) : 8r - 40 = 30 - 5r : 8r + 5r = 30 + 40 : 13r = 70 r = r = 5.3846 : : Check on calc: enter: (5.3846-5)/(6-5.3846) ~ .625 which 5/8
