Answer:

Step-by-step explanation:
To write an equation, use the slope-intercept equation:

M is the slope and b is the y-intercept.
First, find the slope by using the slope formula for when you have two points:

Rise over run is the change in the y-axis over the change in the x-axis. Substitute values:

Simplify parentheses (two negatives make a positive) and simplify:

The slope, m, is 4. Insert this information into the equation:

Now, take one of the points and insert into the slope-intercept formula:

Solve for b, the y-intercept. Simplify multiplication:

Add 20 to both sides and simplify:

The y-intercept, b, is 20. Insert this value into the equation:

Done.
Answer:
Future value, $63,398.79; Interest, $16,798.79
Step-by-step explanation:
The sequence is defined as
an = 3an - 1 + 7
This means that
a2 = 3(a(2 - 1) + 7
a2 = 3a1 + 7
From the information given ,
a1 = - 4
Thus,
a2 = 3 * - 4 + 7 = - 12 + 7
a2 = - 5
a3 = 3(a(3 - 1) + 7
a3 = 3a2 + 7
a3 = 3 * - 5 + 7 = - 15 + 7
a3 = - 8
a4 = 3(a(4 - 1) + 7
a4 = 3a3 + 7
a4 = 3 * - 8 + 7 = - 24 + 7
a4 = - 17
Thus, the first four terms of the sequence are
- 4, - 5, -
