Question

Find the slope of the line passing through the pair of points P(5, V18):Q(118,5) O A. m = 5 O B. m = 1 O c. m=2 O D. m = -1 O E m = none of these

Answer 1

the slope of the line that passes through two points is

$m=\frac{5-\sqrt{18}}{\sqrt{18}-5}$$\begin{gathered} m=\frac{-(\sqrt[]{18}-5)}{\sqrt[]{18}-5} \\ m=-1 \end{gathered}$

so the slope is m = -1
