------------------------------------------------------------ Define the two numbers ----------------------------------------------------------- Let the first number be x. Let the second number be y.
------------------------------------------------------------ Form equations and solve x and y ------------------------------------------------------------ x + 2y = 14 ------------------ (1) 2x + y = 31 ------------------ (2)
------------------------------------------------------------ Substitute y = -1 into (1) ------------------------------------------------------------ x + 2(-1) = 14 x -2 = 14 x = 14 + 2 x = 16
------------------------------------------------------------ Answer: x =16, y = -1 ------------------------------------------------------------
It’s neither, and this is because the slope is not opposite or the same, the same y intercept yes...but there isn’t any parallel or perpendicular features...you can see this when you graph it :)
