x ≤ 4 x = 4 x = 4 Describe the unshaded region. In the unshaded region is x greater than or less than 4? The region is x less than or equals to 4. x ≤ 4 less than First, work out the equation of the line. But as it’s a solid line, it also includes 4 x = 4

In the unshaded region is y greater than or less than 2? Describe the unshaded region. The region is y greater than 2. y > 2 greater than y = 2 and it’s a dotted line, so it does not include 2 First, work out the equation of the line. y = 2

Describe the unshaded region. y  –2 y = -2

Describe the unshaded region. y = 1 y  1

Describe the unshaded region. x = -5 Describe the unshaded region. x < –5

y = 3 x < 4 and y  3 x = 4 x = 4 Describe the unshaded region. The region is x less than 4. x < 4 and y  3 and y less than or equals to 3. x = 4

y = 3 y > –1 and y < 3 –1 < y < 3 y = –1 Describe the unshaded region. y = 3 This inequality should be written as: y = 3 The region is y less than 3. y > –1 and y < 3 –1 < y < 3 and y greater than –1. y = -1 y = –1

Describe the unshaded region. x = -6 x = -1 Describe the unshaded region. –6 < x  –1

Describe the unshaded region. x = -2 Describe the unshaded region. y = 3 x  –2 and y < 3

x + y  6 x + y = 6 Describe the unshaded region. But is this region, less than or greater than? What’s this line called? (3,1) x + y  6 x + y = 6 3 + 1 6  x + y = 6 x + y = 6
