Question

Use the graph to solve the system of linear equations
X-Y=4
4x+y=1

Answer 1

(1,-3)

Explanation:

Since a graph is not attached here, I will go ahead and give you the correct coordinate pair and you can check to see if the point matches on your graph-

Solve using substitution method-

x = y + 4

4x + y = 1

4(y + 4) + y = 1

Distribution-

4y + 16 + y = 1

5y + 16 = 1

-16 + 1 = -15

5y = -15

y = -3

Put it back into the equation-

x - (-3) = 4

x + 3 = 4

x = 1

Answer-

(1,-3)
