Answer:
-5
Step-by-step explanation:
In order to find the slope of two points you need to remember a few things.
(x,_)
The first number in an ordered pair is the x value. That determines the position of a point on the x axis. (Left or right)
(_,y)
The second number in an ordered pair is the y value. That determines the position of a point on the y axis. (Up or down)
(x,y)
Calculating slope
<em>Take the y value from one of your ordered pairs and subtract that value from the other y value. </em>
(10,1) and (5,2)
<em>We will take the numbers 1 and 2.</em>
1-2=-1
<em>Take the x value from the y value you subtracted. Since we used 1 as our first y value we will take its x value 10</em>
(If we started with 2 we would take its x counterpart, which is 5)
10-5=5
<em>Divide -1 by 5 and you get -1/5</em>
(y2-y1) divided by (x2 - x1)
