Question

Slope of the line joining the points A(-3,5) and B(4,-1) is _______.

• A. $\frac{6}{7}$
• B. $\frac{-6}{7}$
• C. $\frac{3}{7}$
• D. $\frac{-3}{7}$

Answer 1

The correct option is B $\frac{-6}{7}$

Let, $x_1=-3,x_2=4,y_1=5\&y_2=-1\therefore \text{Slope of line}AB=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-5}{4-(-3)}=\frac{-6}{7}$
