What is the solution to the systems of equations?

Type your answer as a coordiante.

What would the solution be to this system of linear equations?

• (0,-1.5)

• (1, -3)

• (5,0)

• (0,0)

Solve the system (Mild)

y = -2x - 1

y = -3x - 5

Enter answer as a coordinate with no spaces.

Solve the system (Mild)

y = x - 5

y = 4x + 10

Enter your answer with no spaces as a coordinate.

Find the answer using substitution: Please list your answer as a coordinate (x,y)

Medium

Please list your answer as a coordinate (x,y)

y = 3x - 6

-6x + y = -9

Medium

Write you answer as a coordinate (x,y) with no spaces.

5x + y = -9

7x + 2y = -9

Spicy

List the solution as a coordinate (x,y):

4x + 7y = -1

x + 4y = -7
