well, let's just take the slope using the 2 given points
slope = (y-2)/(3-1) = (y-2)/2
but we are told that the slope is 2 , so
(y-2)/2 = 2
y-2 = 4
y = 6
A line has a slope of 2. It passes through the points (1,2) and (3,y). What is he value of y?
can someone walk me through this without using y=mx+b?
