What is the slope of the line shown below?

Option: A is the correct answer.

The slope of the line is: -4.

We know that the slope of a line denoted by 'm' passing through two points (a,b) and (c,d) is calculated by:

Here we have that the line passes through (-1,8) and (2,-4).

i.e. (a,b)=(-1,8) and (c,d)=(2,-4)

Hence,

Hence, the slope is:    -4
