Answer:
b=3a/8
a=8b/3
Step-by-step explanation:
b/a=k ( k is the constant proportional)
3/8=9/24=15/40
b/a=3/8
b=3a/8
a=8b/3

Hello! Your figures are missing, so I could help you in a general way. The Slope-intercept form of the equation of a line is given by the form:

Case 1:

If the slope is positive, we will have a line as the form illustrated in figure 1. So as x increases y also increases.
Case 2:

If the slope is negative, we will have a line as the form illustrated in figure 2. So as x increases y decreases.
Case 3:

If the slope is zero, we will have a line as the form illustrated in figure 3. here we have a constant function.
Case 4:
m: undefined
If the slope is undefined, we will have a line as the form illustrated in figure 4.

Answer:
90
Step-by-step explanation:
A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and Vice-chair are there ?
This is calculated using the Permutation formula
nPr = n!/(n - r)!
Where:
n = 10 people
r = 2 = 2 positions to be filled , Chairman and Vice chairman
Hence:
10P2 = 10!/(10 - 2)!
= 90 ways
