Question

find the slope of A ( a + b , 4m - n ) and B ( a - b , m + 2n )

Answer 1

Solution:-

$slope = \frac{y2 - y1}{x2 - x1} \\ \\ slope = \frac{m + 2n - (4m - n)}{a - b - (a + b)} \\ \\ slope = \frac{m + 2n - 4m + n}{a - b - a - b} \\ \\ slope = \frac{3n - 3m}{ - 2b} \\ \\ slope = \frac{3m - 3n}{2b} \\ \\ slope = \frac{3}{2} \binom{m - n}{b}$
