The following system of linear equations is solved by graphing them on the coordinate plane. y=3x−2y=−35x−1

Which ordered pair is the best approximation of the solution to the system?

(0,−1)

(1,1)

(−1,0)

(−1,−1)

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units
