If a system of equations has one and only one solution, what does the graph look like? 

• intersecting lines

• parallel lines

• one horizontal and one vertical line

• coinciding lines (overlapping)

Solve the following systems of equations using substitution:

y = 3 - x

3y + x = 5

• No solution

• (1, 2)

• (3, 0)

• (2, 1)

6x = y

3y - 4x = 42

• (3, 18)

• (8, 2)

• (2, 8)

• (1, 6)

x = 3y

2x - y =10

• (4, 5)

• (1, 1)

• (5, 8)

• (6, 2)

y = x + 1

2x - 3 = y

• (3, 5)

• (5, 4)

• (4, 3)

• (4, 5)
