Write down the inequalities that are represented by the following diagrams.

There is an open circle at 11 with shading to the left, which means $x < 11$.

There is a solid circle at 18 with shading to the right, which means $x \ge 18$.

B)

There is a solid circle at -2 with shading to the right, which means $x \ge -2$.

There is an open circle at 6 with shading to the left, which means $x < 6$.

C)

There is a solid circle at 0 with shading to the right, which means $x \ge 0$.

There is an open circle at 16 with shading to the left, which means $x < 16$.

D)

There is an open circle at 5 with shading to the left, which means $x < 5$.

There is an open circle at 15 with shading to the right, which means $x > 15$.

E)

There is a solid circle at -2 with shading to the right, which means $x \ge -2$.

There is a solid circle at 4 with shading to the left, which means $x \le 4$.

For the given points $P_1 (3, 2)$ and $P_2 (-1, -2)$.

A) Find the slope (m).

B) By using the gradient - point Formula ($m = \frac{y_1 - y}{x_1 - x}$), formulate the function in the form $y = mx + c$.

C) What is the y - intercept?

Substitute $x=0$ into the equation $y = x - 1$.
