Find slope of line joining (1, 2) and (4, 11): - Vidyadip

MCQ

Find slope of line joining (1, 2) and (4, 11):

A
$\frac{1}{3}$
B
$3$
C
$9$
D
$\frac{1}{9}$

✓

Answer

$3$

Solution:

We know, slope of line joining two points (x₁, y₁) and (x₂, y₂) is given by $\frac{{\text{y}}_{2}-{\text{y}}_{1}}{{\text{x}}_{2}-{\text{x}}_{1}}$

So, slope of line joining (1, 2) and (4, 11) is $\frac{11-2}{4-1} = \frac{9}{3} = 3$
