Find the slope of the line that passes through (10,1) and (5,2) PLEASE DO A STEP BY STEP EXPLANATION i learn nothing from my teacher :/

-1/5

Slope is given by the change in y over the change in x.

Change in y: 2-1= 1

Change in x: 5-10= -5

-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

Take the y value from one of your ordered pairs and subtract that value from the other y value.

(10,1) and (5,2)

We will take the numbers 1 and 2.

1-2=-1

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

(If we started with 2 we would take its x counterpart, which is 5)

10-5=5

Divide -1 by 5 and you get -1/5

(y2-y1) divided by (x2 - x1)

:) Hope this helped
