Line M is represented by the following equation: x − y = 8

Which equation completes the system that is satisfied by the solution (18, 10)? (4 points)
2x − y = 26
x + y = 18
2x − 2y = 36
x − y = −28

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

the answer is 48m^2!

step-by-step explanation:

b.-4 units

all you   do is count how many times you move
