I'm assuming you are finding the equation of the line of Line J
Slope-intercept form: y = mx + b
[m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis]
For lines to be perpendicular, the slopes have to be negative reciprocals of each other. (basically changing the sign (+/-) and flipping the fraction/switching the numerator and the denominator)
For example:
slope = 2 or 
Perpendicular line's slope = 
[changed sign from + to -, and flipped the fraction]
slope = 
Perpendicular line's slope = 
[changed sign from - to +, and flipped the fraction]
Since you know the slope is 3, the perpendicular line's slope is 
. Plug this into the equation
y = mx + b
To find b, plug in the point (3, 8)
8 = -1 + b Add 1 on both sides to get "b" by itself
8 + 1 = -1 + 1 + b
9 = b
Answer:
Ashley would have to pay an additional $608.52 in interest when the length of the loan changes from 3 years to 5 years.
Step-by-step explanation:
Although the problem gives us the initial amount of the balance ($4000) and the interest rate (13%), we are really only concerned with the total amount Ashley will make in payments in three years versus five years. If she pays $134.78 for three years, that is 36 months, or $134.78 times 36 which is equal to $4852.08. However, if she decides to take longer to pay it and instead pays $91.01 for five years, or 60 months, then her total amount paid would be $5460.60. To find the difference between these two, simply subtract $5460.60-$4852.08 to get $608.52.
The answer is five
