Q:
Find the value of y if the line passing through (1/2,y) and (-3,-10/9) has a slope of 2/7.
---------------------------------------------------------------------------
A:
slope, m = %28-10%2F9+-+y%29%2F%28-3+-+1%2F2%29 = 2/7
%28-10%2F9+-+y%29 = %282%2F7%29%28-3+-+1%2F2%29, multiply both sides by -1
%2810%2F9+%2B+y%29 = %282%2F7%29%283+%2B+1%2F2%29
y = %282%2F7%29%283+%2B+1%2F2%29+-+10%2F9 = highlight%28-1%2F9%29
