Question

What is the slope of the line that passes through the points (2,1) and (-4,-5)

Answer 1

Hi there!

Since the slope of the line is any two coordinate points on the line solved by the formula y2 - y1 / x2 - x1, we can follow this formula:

1 - -5
= 1 + 5
= 6

2 - -4
= 2 + 4 
= 6

= 6/6
= 1

So, the slope would be 1. 

Hope this helps!

Answer 2

$\text{Slope =} \dfrac{1+5}{2+4} = \dfrac{6}{6} = 1$
