Question

Find the slope of the line graphed below. 4. 3+ I - -G 4 5 -3 -4 5

Answer 1

Given data:

The first point on the line is (a, b)=(-1, -1).

The second point on the line is (c, d)= ( 4, -5).

The slope of the line is,

$m=\frac{d-b}{c-a}$

Substitute the given values in the above expression.

$\begin{gathered} m=\frac{-5-(-1)}{4-(-1)} \\ =\frac{-5+1}{4+1} \\ =\frac{-4}{5} \\ =-\frac{4}{5} \end{gathered}$

Thus, the slope of the given line is -4/5.
