There is no picture but I'll help you find out:

The inequality is easy because an inequality says,

y > mx + b (This is just an example)

m = slope

b = y- intercept

What about the sign?

If the circle in the graph which is at the y-intercept (b) is OPEN than it's either < or > depending on where it's going, if it's going to the right on a number line than it's >, however if it goes left than it's <.

What about the AND EQUAL TO sign?

Well same rules apply, however if the circle is CLOSED than it should be ≤ or ≥, same rules apply, if it goes right or left it's the same rule the only thing that changes is the and equal to, if circle is closed.

Example:

slope: 1/2

y-intercept: -9 (and the line is shaded to the right)

Open circle:

Equation: y > 1/2x - 9

Example 2:

slope: 3/4

y-intercept: -9 (is shaded to the left (less than))

(shaded)Closed circle:

Equation: y ≤ 3/4x - 9
