Please answer fast will mark brainliest Evaluate r/2 + (7/8 - s)

when r=1 and s =1/2

OA) 7/8
OB)3/2
OC)15/8
OD)19/8

1. 5/82.95% is better than 7/8

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
