 Question 146690: A line passing through (4, 11) and (1, y) is parallel to a line with slope 2. What is the value of y? Can someone show me how to work this problem out. ThanksAnswer by nerdybill(6948)   (Show Source): You can put this solution on YOUR website!A line passing through (4, 11) and (1, y) is parallel to a line with slope 2. What is the value of y? . If two lines are parallel, their slopes MUST be the same. . We can calculate the slope of a line given two points by using: slope = (y2-y1)/(x2-x1) . if we assign the following: (x1,y1) is (4, 11) and (x2,y2) is (1, y) . Now, simply "plug in" the given values and solve for y: slope = (y2-y1)/(x2-x1) 2 = (y-11)/(1-4) 2 = (y-11)/(-3) -2/3 = y-11 11-2/3 = y 33/3 - 2/3 = y 31/3 = y or 10.333 = y
