Question

Find the slope of the line passing through the following pairs:

(-4 , 5) and (2, 3)

• A. $-3$
• B. $-\frac{1}{3}$
• C. $\frac{1}{3}$
• D. $3$

Answer 1

Answer: (B)

$-\frac{1}{3}$

Slope of the line passing through points $(x_1,y_1)$
and $(x_2,y_2)$ $=$ $\frac{y_2-y_1}{x_2-x_1}$

Hence, slope of the line passing through $(-4,5)$ and $(2,3)=\frac{3-5}{2-(-4)}=\frac{-2}{6}=\frac{-1}{3}$
