Answer:
You start at -9
-Open circle
-shade towards the right (where all the positive numbers are)
Open circle - ones that don't have a greater than or equal to. If it does then it's a closed one.
Shade towards the right cause y is less than 9

Que in english this is what
Answer:
Variable "m"
Step-by-step explanation:
Hello!
The equation
is perhaps the most used equation when representing a line. The parts of the equation:
- y = output, y-value, ordinate...
- m = slope, rate of growth, rise over run...
- x = input, x-value, abscissa...
- b = y-intercept
____________________________________________
Let's use an example: y = 2x + 5
We want to find the y-value when x is 2.
To solve, simply plug in 2 for x:
- y = 2(2) + 5
- y = 4 + 5
- y = 9
So, the coordinate when x is 2 is (2,9), remember that coordinates are written in (x,y) format.
Image: y = 2x + 5
