What is the slope of the line represented by the equation

Pie

Answer:

The slope is -3/4

Step-by-step explanation:

3x+4y = 8

We want to get the equation in slope intercept form

y = mx+b where m is the slope

Subtract 3x from each side

3x+4y-3x= -3x+8

4y = -3x+8

Divide by 4

4y/4 = -3x/4 +8/4

y = -3/4x +2

The slope is -3/4 and the y intercept is 2

Step-by-step explanation:

Given as :

The principal amount for room loan = $ 3,800

The rate of interest applied = 11% compounded annually

The time period of loan = 3 years

Now,<u> From Compounded method :</u>

Amount = Principal × $(1+\dfrac{\textrm rate}{100})^{\textrm time}$

or, A = $ 3,800 × $(1+\dfrac{\textrm 11}{100})^{\textrm 3}$

or, A = $ 3,800 × (1.11)³

or, A = $ 3,800 × 1.3676

∴ A = $ 5,196.88

So, Amount after 3 years = A = $ 5,196.88

Hence The loan amount after 3 years is $ 5,196.88 Answer
