+42 Look at the gradients(\(M\)) for both lines
Line 1 gradient = -4 = \(M_1\)
Line 2 gradient = 1 / 4 = \(M_2\)
Definition for a perpendicular line is when the gradient(\(M\)) satisfies:
\(\frac{-1}{M_1}\) is perpendicular to \(M_2\)
IT IS NEITHER!! THE LINES CRISS-CROSS.
Here is how you plot it:ContourPlot[{y = 14 - 4 x, -x + 4 y = 14}, {x, 25/17, 59/17}, {y, 53/17, 87/17}]
