The flags are all the same size and are space equally along the line. Calculate the length of the sides of each flag, and the space between flags by making a system of equations and solving that system..

Step-by-step explanation:

Let the space between flags be "x" and the flag's side is "y"

2x + 3y = 80   ║ × ( - 2 )

5x + 6y = 170

- 4x - 6y = - 160 ..... ( 1 )

5x + 6y = 170 ..... ( 2 )

( 1 ) + ( 2 )

x = 10

2(10) + 3y = 80

y = 20

The space between flags is 10 cm

The flag's sides are the same size and is 20 cm

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
