First, we find the y-intercept, which in this case is -1, because that's where the line crosses the y-axis.

y = mx + b

Where 'm' is the slope and 'b' is the y-intercept, therefore -1 replaces 'b':

y = mx - 1

Now let's take any two points on the line and find the slope.

m = y2-y1/x2-x1

(0, -1) and (1, 2)

m = (2 + 1)/(1 - 0)

m = 3/1

m = 3

So the slope is 3, plug this in the equation also:

y = 3x - 1

If the rr is equal to 25%, what is the value of the money multiplier (simple deposit multiplier)? if $35,000 in cash is taken fr

DENIUS [597]

The money supply in the economy is $1025302.6

Bank loans or invests its excess reserves to earn greater hobby. A one-dollar boom inside the financial base reasons the money deliver to boom through more than one dollar. The growth inside the money supply is the cash multiplier.

The money multiplier is the primary can used to calculate what a change in reserves could do to the money supply. The method for the cash multiplier is 1/r where r is the reserve ratio. once one has calculated the money multiplier, they might then multiply that through the exchange in reserves.

The money multiplier is critical in macroeconomics because it determines the cash supply, which affects interest charges. it is also critical in banking because it impacts economic coverage and the steadiness of the banking region.

Write the final equation using the slope-intercept form perpendicular to 3y = x − 4 and passes through the point (−2, 1)

stealth61 [152]

Answer:

y=-3x-5

Step-by-step explanation:

given equation:

3y=x-4

slope intercept form is y=mx+b

(m is the slope, b is the y intercept)

divide by 3

y=1/3x-4/3

perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.

so to find the slope of the perpendicular line, use this equation:

1/3m=-1

multiply by 3

m=-3

the slope of the new line is -3.

here is our equation so far:

y=-3x+b

now, we need to find b.

Since the equation of the line passes through the point (-2,1) we can substitute that into the equation to find b

1=-3(-2)+b

multiply

1=6+b

subtract 6

-5=b

so the line is y=-3x-5

Hope this helps!
