How do i find the slope and y intercept ?
2 answers:
Here are the instructions. Then we'll do your specific problem.
Step 1: Solve the equation for y, and write it in the form y = mx + b.
Step 2: The slope is m, and the y-intercept is b.
Now let's start.
-2x - 5y = -20
To solve for y, we first add 2x to both sides.
-5y = 2x - 20
Now we divide both sides by -5.
Now we compare what we got with the form, y = mx + b.
We see that m = -2/5, and b = 4. m is the slope, and b is the y-intercept.
slope: -2/5
y-intercept: 4

Answer:
V = $1213.03
Step-by-step explanation:
We can determine the amount of money after 15 years with the given formula:
(1)
Where:
V: is the value of the account in t years =?
P: is the principal initially invested = $686
r: is the rate of interest = 3.8% = 3.8/100 = 0.038
t: is the time = 15 years
By substituting the above values into equation (1) we have:
Therefore, the amount of money is $1213.03.
I hope it helps you!
