Step-by-step explanation:

in the picture

The slope of a line that contains the  points (0, -2), (3, 1) is 1 and points (0.-2), (2.-8) is -3

Solution:

2. For the first problem,  

The points are and

Let us assume that the slope is m.

We know the slope on a point

Now substituting the value of the points we get,

3. For the second problem,

The points are and

Let us assume that the slope is m1

We know the slope on a point

Now putting the value of the points we get,

grab rope, tie a loop-de-loop, put it around ur neck, now jump while its tied to a high place. now your shoes are cool.
