Question

Find slope of a line through points(1, 2) and ( 3, 8). ​

Answer 1

Answer:

3 is the slope of the line

Given

$\bullet~~(x_1,y_1)=(1,2)$

$\bullet~~(x_2,y_2)=(3,8)$

Solution

$\underline{\boxed{\rm Slope = \dfrac{\triangle y}{\triangle x}=\dfrac{y_2-y_1}{x_2-x_1}}}$

$\implies~~\dfrac{8-2}{3-1}=\dfrac{6}{2} =3$
