1) 1/3

2)6

3)-6

4)-3

5)-1/3

6) 3

or 3

Step-by-step explanation:

To find the slope find two coordinates and set up the equation

For the coordinates (0,2) and (2,8) y2 is 8 and y1 is 2. x2 is 2 and x1 is 0. you have to do subtraction first. 8-2 = 6 and 2-0 = 2

Now we have the equation

this can be simplified to  

the answer is simply just 6n add the two together as they have an n

just sum

10 + 10 = 20
