Answer (Note: the bold are answers):
First question answer:
Point = (3,1)
Slope = 3
y = 3x + b
(1) = 3(3) + b
1 = 9 + b
1 - 9 = b
-8 = b
y = 3x - 8
The second question answer:
y = mx + b
Get two points:
(3,-7) and (4,-11)
m = -11 - (-7) / 4 - 3
m = -11 + 7 / 1
m = -4 / 1
m = -4
b = + 3
y = -4x + 3
Answer:
= $3,888.89
Step-by-step explanation:
First, calculate the money multiplier(MM); which is the amount of money that is generated by the banks for each dollar of reserve. In this case, it describes how a deposited amount increases the total supply of money.
Money Multiplier = 1 / reserve ratio
Reserve ratio = 9% or 0.09
Therefore, money multiplier = 1/0.09 = 11.1111
Next, use the reserve ratio to calculate the amount of increase in money supply;
= 11.1111 * $350
= $3,888.89
Y=ax+b
3=-8(0)+b
3=0+b
3=b
Y=-8x+3
(I think this is right, but u might want to double check)
