PLSS HELP with 1 3 and 4

1.) slope is 6

2.) slope is -4

4.)slope is undefined

Step-by-step explanation:

1.) For one we can use the equation y2-y1/ x2-x1

First, pick any 2 points that you want to use to plug into the equation

(0, -3) and (1, 3)

Next, plug in and solve!

3-(-3)/ 1-0= 6

The slope is 6

2.) We can use this same equation for the problem and plug in!

(-1, 5) (2,-7)

-7- 5/ 2-(-1)= -4

The slope is -4!

4.) Use the same equation and find the slope!

(8, 1) and (8, 2)

2-1/ 8-8= undefined

Because we cannot divide by a 0 the slope is undefined!

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

a = 11 : 4

b = 38

c = 1 for every 6
