Question

Slope of the line joining the points (2, 1) and (6, 7) is _______.

• A. $\frac{3}{2}$
• B. $\frac{2}{3}$
• C. 1
• D. 0.0

Answer 1

The correct option is A $\frac{3}{2}$

Let the points ($x_1$, $y_1$) and ($x_2$, $y_2$) be (2, 1) and (6, 7) respectively.
Slope of a line joining two points ($x_1,y_1)$ and ($x_2,y_2)$ $=\frac{y_2-y_1}{x_2-x_1}=\frac{7-1}{6-2}=\frac{6}{4}=\frac{3}{2}$
