I might just give two of them.
28. y=45°, 
13x13=169
169/2=84.5
√84.5=x
x=2√21+√2/2
31. (5√2)²=50
50/2=25
x=√25=5
(5√2)²+(5√2)²=100
y=√100=10
Those are your answer.

SHOW YOUR WORK!!! Marking best answer as brainliest :))
Wewaii [24]

Answer:

-25

Step-by-step explanation:

You must first pick two points.  I picked the points of (4, 400) and (8, 300).  You can pick different points and still get the right answer.

Subtract the y's and the x's.  Divide the difference of y by the difference of x.

400 - 300 = 100

4 - 8 = -4

100/-4 = -25

The slope, or rate of change, is -25.
