Question

find the slope of the line perpendicular to the line joining the points (1,7) &(4,3)

Answer 1

➡HERE IS YOUR ANSWER⬇

The slope of the line joining the points (1,7) and (4,3) is

$= \frac{7 - 3}{1 - 4} \\ \\ = \frac{4}{ - 3} \\ \\ = - \frac{4}{3}$

If m be the slope of the above perpendicular line, then

$(m)( - \frac{4}{3} ) = - 1 \\ \\ or \: \: m = \frac{3}{4}$

So the slope of the perpendicular line is = 3/4.
