Y - INTERCEPT:
y + 4 = -4 ((0) - 2)
y + 4 = -4 (-2)
y + 4 = 8
y = 4
(0, 4)
STANDARD FORM:
Ax + By = C
y + 4 = -4x + 8
4x + y + 4 = 8
4x + y = 4
X INTERCEPT:
(0) + 4 = -4 (x - 2)
4 = -4 (x - 2)
4 = -4x +8
-4 = -4x
x = 1
(1, 0)
PERPINDICULAR LINE:
y + (1) = (1/4) (x - (5))
y + 1 = 1/4x - 5/4
-1/4x + y + 1 = -5/4
-1/4x + y = -9/4
x - 4y = 9
X INTERCEPT OF PERPINDICULAR LINE:
x - 4(0) = 9
x - 0 = 9
x = 9
(9, 0)
PARALLEL LINE:
y + (-2) = -4 (x - (0))
y - 2 = -4x + 0
4x + y - 2 = 0
4x + y = 2
ORDERED PAIR FOR PARALLEL LINE:
4(-2) + y = 2
-8 + y = 2
y = 10
(-2, 10)

The distance from (0,1) to (0,6) is 5 units.
The area of a triangle is
Area = bh/2
10 = 5b/2
20 = 5b
b = 4
The distance of the base is 4 units. So, from (0,1) count 4 units to the right but on the same y coordinate.
So the point is in (4, 1).

9r(r + 3) - 2r(r - 4) = 9r^2 + 27r - 2r^2 + 8r
Now we want to combine like terms:
9r^2 + 27r - 2r^2 + 8r = 7r^2 + 35r

Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $7500
r = 6% = 6/100 = 0.06
Assuming the interest was compounded annually, then
n = 1 because it was compounded once in a year.
t = 4 years
Therefore,
A = 7500(1 + 0.06/1)^1 × 4
A = 7500(1.06)^4
A = $9468.6
The interest that they would have earned after 4 years is
9468.6 - 7500 = $1968.6
