Answer:
Parallel line:
![y=-\frac{4}{5}x+\frac{9}{5}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B4%7D%7B5%7Dx%2B%5Cfrac%7B9%7D%7B5%7D)
Perpendicular line:
![y=\frac{5}{4}x-\frac{1}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B4%7Dx-%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
we are given equation 4x+5y=19
Firstly, we will solve for y
![4x+5y=19](https://tex.z-dn.net/?f=4x%2B5y%3D19)
we can change it into y=mx+b form
![5y=-4x+19](https://tex.z-dn.net/?f=5y%3D-4x%2B19)
![y=-\frac{4}{5}x+\frac{19}{5}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B4%7D%7B5%7Dx%2B%5Cfrac%7B19%7D%7B5%7D)
so,
![m=-\frac{4}{5}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B4%7D%7B5%7D)
Parallel line:
we know that slope of two parallel lines are always same
so,
![m'=-\frac{4}{5}](https://tex.z-dn.net/?f=m%27%3D-%5Cfrac%7B4%7D%7B5%7D)
Let's assume parallel line passes through (1,1)
now, we can find equation of line
![y-y_1=m'(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%27%28x-x_1%29)
we can plug values
![y-1=-\frac{4}{5}(x-1)](https://tex.z-dn.net/?f=y-1%3D-%5Cfrac%7B4%7D%7B5%7D%28x-1%29)
now, we can solve for y
![y=-\frac{4}{5}x+\frac{9}{5}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B4%7D%7B5%7Dx%2B%5Cfrac%7B9%7D%7B5%7D)
Perpendicular line:
we know that slope of perpendicular line is -1/m
so, we get slope as
![m'=\frac{5}{4}](https://tex.z-dn.net/?f=m%27%3D%5Cfrac%7B5%7D%7B4%7D)
Let's assume perpendicular line passes through (2,2)
now, we can find equation of line
![y-y_1=m'(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%27%28x-x_1%29)
we can plug values
![y-2=\frac{5}{4}(x-2)](https://tex.z-dn.net/?f=y-2%3D%5Cfrac%7B5%7D%7B4%7D%28x-2%29)
now, we can solve for y
![y=\frac{5}{4}x-\frac{1}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B4%7Dx-%5Cfrac%7B1%7D%7B2%7D)
Let 4 + 3x = u
then 3dx = du
or, <span>1/3∫<span>u√</span>du
</span>
= <span>1/3<span>u^<span>3/2</span></span>/(3/2)
</span>
= <span>2/9∗(4+3x<span>)^<span>3/2

Negative Exponent Rule:
this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents.

The answer is "A. greater than" because if the number of edges increase, the measure of each exterior angle increases too!
Hope this helps. :)
