Answer:

The parallel line would be y = 1 and the perpendicular line would be x = 3.

Step-by-step explanation:

In order to find a line parallel to y = 5, we must first note that y = 5 is a horizontal line. This means to be parallel, the line must also be horizontal. All horizontal lines are written in the form of y = (just a number). Since we can see the value of y in the ordered pair as 1, we know the equation is y = 1.

The exact opposite logic can be used to find the perpendicular line. Since the first line is horizontal, the next one will be vertical, which are written as x = (a number). We again look to the ordered pair to determine the number and write the equation as x = 3

Step-by-step explanation:

You would start by using one of the equations to find y with x in the equation. You want to pick the easier one. I picked this one because it was evenly divisible.

5x+5y=50

5x=-5y+50

x=-y+10

Then you what to plug that in to the second equation and solve for y.

3(-y+10)+4y=32

-3y+30+4y=32

-3y+4y=2

y=2 (because you combined like terms)

Then you would plug back into the first equation and solve for x.

5x+5(2)=50

5x+10=50

5x=40

x=8

x=8, y=2
