Use the slope intercept form; y=mx+b where m is the slope and b is the y-intercept
Answer:
Option 1
Step-by-step explanation:
The formula of constant porpotionality is

or

where k is the constant of porpotionality.
This equation is direct variation so we will use

The equation is in the form

1.5 is in k place so the constant of porpotionality is 1.5

Answer:
-3
Step-by-step explanation:

First, you can factor out a 6:

Next, you can factor the quadratic:

Since the only value of x that could set this equation equal to 0 is -3, that is the answer. Hope this helps!
Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. The principal at the end of 3 years is $248.
<h3>What is simple interest?</h3>
Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,
SI = (P × R × T)/100
where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.
The principal at the end of 3 years is,
Principal after 3 years = P + (P × R × T)
= $200 + ($200 × 0.08 × 3)
= $200 + $48
= $248
Hence, the principal at the end of 3 years is $248.
