Answer:
Parallel line:

Perpendicular line:

Step-by-step explanation:
we are given equation 4x+5y=19
Firstly, we will solve for y

we can change it into y=mx+b form


so,

Parallel line:
we know that slope of two parallel lines are always same
so,

Let's assume parallel line passes through (1,1)
now, we can find equation of line

we can plug values

now, we can solve for y

Perpendicular line:
we know that slope of perpendicular line is -1/m
so, we get slope as

Let's assume perpendicular line passes through (2,2)
now, we can find equation of line

we can plug values

now, we can solve for y

Answer:
75%
Step-by-step explanation:
Write down 11 dollars for one advertisement so your x value is unknown so you plug in your y value
Answer:
The percent charge of Kanna's DS is 50%
Step-by-step explanation:
we know that
A Nintendo DS takes 4 hours to charge fully (100%)
4 hours is the same that 240 minutes
using proportion
Find out what percentage represent 108 minutes

Remember that
Kanna Kamui charge her DS from 5%
so

therefore
The percent charge of Kanna's DS is 50%
The first statement show that after print the statement, the compiler will leave the line and start the next statement on fresh line.
While the second statement show that after print statement the compiler will continue print next statement without drop to another line.
