Answer:
Spencer and Abigail are correct
Lauren is incorrect
Step-by-step explanation:
Spencer and Abigail are correct
Slope = change in y ÷ change in x
Or 
Let
= (3, -1)
Let
= (5, 4)

This is Spencer's method
Let
= (5, 4)
Let
= (3, -1)

This is Abigail's method
It doesn't matter which point you label as point 1 and point 2, as long as you carry out the slope calculation correctly.
Lauren's calculation is wrong as she calculated her slope as:
where it should have been 
The answer is D) 5 and 5/8ths because 2 1/2 + 3 3/4 + 4 1/8
= 10 3/8
10 3/8 + 5 5/8 = 16
Step-by-step explanation:
B: The x axis is the horizontal one. If we look at the graph, there are actually two spots where the line crosses the x axis. It looks to be between -2 and -1 as well as 1 and 2
D: For vertical parabolas such as this, the axis of symmetry is the x coordinate of the vertex. The vertex is essentially the middle point, that, for this graph, is at the bottom. The axis of symmetry is x=0 as that is the x coordinate of the vertex.
E: f(x), in 2D graphs, is typically y, as is the case here. As this parabola opens upward, the minimum point is the vertex, which seems to be -3 for this graph. As the graph seems to be x²-3 or something like that, there is nothing limiting x from being infinity, and when x is equal to infinity in this function, y is as well. Thus, the maximum is infinity.

In order to define a term, we must have a definition of <u>all of the words</u> used to describe it. As this progresses, we would have a never-ending list of words to define; at some point, we must accept a few basic building blocks as being undefined.</span>
