Question

Match the Inequality to its graph

1. y > x + 2

2. y ≥ x + 2

3. y < x + 2

4. y ≤ x + 2

Answer 1

Similar to y = mx + b

The only difference is that with the inequality sign, it will determine which side you shade and whether it's solid or dashed.

y > x + 2

Plot the y intercept at 2 or (0,2) and apply rise/run,

x/1 = x

x = 1/1 so rise 1 and run 1

It's greater than so shade above the line. And it's not \(\ \sf equal ~ to \) therefore it will be \(\ \sf dashed \)
