Question

Find the slope of the line passing through the pair of points P(5, V18): Q(V18,5) O Am=5 Bm=1 o c.mo2 Dm

Answer 1

hello

to solve this question, let's use equation of a slope with the given lines

slope (m) =

$m=\frac{y_2-y_1}{x_2-x_1}$

let's identify our points

$\begin{gathered} y_2=5 \\ y_1=\sqrt[]{18} \\ x_2=\sqrt[]{18} \\ x_1=5 \end{gathered}$

put the values into the equation

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{5-\sqrt[]{18}}{\sqrt[]{18}-5} \\ m=-1 \end{gathered}$

from the calculation above, the value of m = -1 which corresponds to option d
