Question

Which expression can be used to find the slope of a line containing the points (-3,2) and (7,-1)

Answer 1

The right expression is -1-2/7-(-3) which then gives you -3/10

Answer 2

Answer: $\dfrac{-1-2}{7-(-3)}$

Step-by-step explanation:

The slope of a line passing from (a,b) and (c,d) is given by :-

$\text{slope}=\dfrac{d-b}{c-a}$

Given points of a line : (-3,2) and (7,-1)

Substitute a=-3, b=2, c=7, d=-1 in the above formula of slope we get,

The slope of a line containing the points (-3,2) and (7,-1) will be :-

$\text{slope}=\dfrac{-1-2}{7-(-3)}$
