Answer:
y-intercept: (0,6)
slope = -2
equation: y = -2x + 6
Step-by-step explanation:
1) First, identify the y-intercept. The y-intercept is the point at which the line intersects the y-axis. We can see that the line crosses the y-axis at (0,6), so that must be it.
2) Now, find the slope. Pick two points from the line. I chose (0,6) and (3,0). Then, substitute the two points' x and y values into the slope formula and solve:
So, the slope is -2.
3) With the found information, use the slope-intercept formula to write the line's equation. Substitute values for the
and
.
represents the slope, so substitute -2 in its place.
represents the y-intercept, so substitute 6 in its place. This gives the following equation:
Using simple interest, and considering a loan of $5,000, it is found that:
a) Her monthly payment is of $74.17.
b) She will pay back $8,900.
c) The total interest amount is of $3,900.
The amount of money after <u>t years</u> in <em>simple interest</em> is modeled by:
In which:
- A(0) is the initial amount.
- r is the interest rate, as a decimal.
In this problem:
- The loan is of $5,000, hence
.
- The APR is of 7.8%, hence
- 10 years, hence
Item b:
She will pay back $8,900.
Item a:
$8,900 will be paid in 10 x 12 = 120 months, hence:
Her monthly payment is of $74.17.
Item c:
<u>Loan of $5,000, pays back $8,900</u>, hence:
8900 - 5000 = 3,900
The total interest amount is of $3,900.
