Well, to find slope of 2 points you need to use the point-slope formula: y2-y1/x2-x1. I attached a picture of my work so you can see what i'm talking about, but i'm going to explain what I did.

1. I labeled the coordinate pairs with x1, y1 and x2, y2. Since we know a coordinate pair looks like this (x,y), we take the first X and Y values and label them x1 and y1. Then, we take the second set of X and Y values and label them x2 and y2.

2. I plugged the numbers in where they belong in the formula. For example, when you label x1 should be -2. So on our formula, all we do is replace x1 with -2. Do that with all your numbers until the whole formula is filled in.

3. Then, solve it. You should get 0/-24 and you should always simplify your answer. However, in this situation, you cannot simplify. So, your answer is 0/-24.

Hope this helps :)

Explanation:

I love questions like these.

Ok so the formula for slope is


(y2 - y1)/(x2 - x1)

In an ordered pair the first number is (x) and the second is (y). (x, y).

So that means y2 is the (y) of the second given pair and y1 is the y of the first given pair.

And x2 is the (x) of the second given pair, and the x1 is the (x) of the first given pair.

So now we fill in the formula.


(8 - 8)/( - 22 - ( - 2))

simplify


(0)/( - 20)

0 divided by anything is still 0, so our slope is 0.
