1. 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

2. 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
