Answer 1

M= (y2-y1)/(x2-x1). the formula stated is how to find the slope of a line with two known points. plug in your numerical values and solve.

Answer 2

`m=(-1-2)/(7+3)`

Explanation:

we know that

The formula to calculate the slope between two points is equal to

`m=(y2-y1)/(x2-x1)`

we have

`A(-3,2)\ B(7,-1)`

Substitute the values

`m=(-1-2)/(7+3)`

`m=(-3)/(10)=-0.3`
