2/8 bell 6

The solution (x, y) to a system of equations is the point where they...? 

• Run off the graph
• Don't touch
• Intersect
• Exist

Solve by Substitution:

x = -3y - 17

2x + 3y = -7

• (1, -20)

• (3, 0)

• (-5, -2)

• (10 , -9)

Solve the system of equations using substitution:

-4x + 4y = 8

y = -2x - 10

• (-4, -2)

• (12, -34)

• (4, -18)

• (-2, -6)

• No solutions (one is the same, one is different)

• One solution (both are different)

• Infinite solutions (both are the same)

• No solutions (one is the same, one is different)

• One solution (both are different)

• Infinite solutions (both are the same)
