Please when you answer this show work how you did it.

5/2

Step-by-step explanation:

slope equal to change in Y out of change in X.

(3, 2), (-1,-8)

to get the change in Y you take the second Y -8 minus the first 2=-10

to get change in X take second X-1 minus the first 3 = -4

-10/-4 negative divided by negative is positive

answer = 5/2 after simplification by two or 2.5 after division

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
