The stem-and-leaf plot for each set of data can be displayed as shown in the images attached below (see attachment).
<h3>What is a Stem-and-leaf Plot?</h3>
A stem-and-leaf plot is used to display a data distribution, for example, 25 and 26 can be displayed as:
2 | 5, 6.
Thus, the stem-and-leaf plot for each set of data can be displayed as shown in the images attached below (see attachment).

The first thing you have to do is:
subtract: 11-5
Then subtract: -4-(-2)
then you put it as a fraction: 6/-2 or -3
That -3 would be considered the slope.
So now you have: y=-3x+ b
So what you have to do is plug in one of the points into the equation to find out what b is.
For example: 11 = -3(-4) + b
11=12 + b
-12 -12
b = -1
So the answer is: y = -3x -1
<span>The vertex form of a quadratic is given by. y = a(x – h)2 + k, where (h, k) is the vertex. The "a" in the vertex form is the same "a" as. in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down.</span><span>
