 Question 626564: 1. Find the value of b so that 3x-2y=4 is parallel to 6x+by=12 2. Find the value of c so that x-3y=c will pass through (2,-1)Answer by stanbon(57407)   (Show Source): You can put this solution on YOUR website!1. Find the value of b so that 3x-2y=4 is parallel to 6x+by=12 The slopes must be the same. 1st equation has a slope of 3/2 2nd equation has aslope of -6/b Solve: -6/b = 3/2 b = -4 ===================== 2. Find the value of c so that x-3y=c will pass through (2,-1) When x = 2, y must be -1. x - 3y = c 2 - 3*-1 = c 2 + 3 = c c = 5 ============== cheers, Stan H.
