Answer:
nonlinear
Step-by-step explanation:
The degree of x in the equation is not 0 or 1, so the function is nonlinear.
_____
<em>Additional comment</em>
Your function graphs as a parabola, not a straight line. A function is only linear if its graph is a straight (non-vertical) line.
The last answer, because the class is being divided into four groups. So the class number is not known, thus it is represented by “w” and divided by four.
Answer: y = -4x - 4
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
Plug in y1 and x1, and m. M is the slope, x1 and y1 are the values for a coordinate. You don't need to plug anything in for y or x, just y1 and x1.
First, find the slope. To find the slope, use this "formula" : 
Find two coordinate points. Let's use (-2,4) and (0,-4). Based on this, we know that y1 is 4, y2 is -4, x1 is -2, and x2 is 0. Plug these into the formula:

Then, pick any point to plug into the equation. Let's use (0,-4)
Finally, plug everything into the equation:
y - - 4 = -4(x - 0)
y + 4 = -4x
y = -4x - 4
