Answer:
Use graph paper to create a scatter plot. Draw the x- and y- axes, ensure they intersect and label the origin. Ensure that the x- and y- axes also have correct titles. Next, plot each data point within the graph. Any trends between the plotted data sets should now be evident.
To find the value of q, we need to find d(-8). Put another way, we need to find the value of d(x) when x = -8





So this means q = 0. Note that -0 is just 0.
===========================================
The value of r will be a similar, but now we use f(x) this time.
Plug in x = 0





Therefore, r = 2.
===========================================
For s, we plug x = 10 into f(x)





So s = 3.
===========================================
Finally, plug x = 10 into d(x) to find the value of t





A shortcut you could have taken is to note how d(x) = -f(x), so this means
d(10) = -f(10) = -9 since f(10) = 9 was found in the previous section above.
Whichever method you use, you should find that t = -3.
===========================================
<h3>In summary:</h3><h3>q = 0</h3><h3>r = 2</h3><h3>s = 3</h3><h3>t = -3</h3>
Answer:
y = -x - 1
Step-by-step explanation:
soo since we already know the slope we can subsitute it to the slope form equation
y = mx + b
y = -x + b
now to find the y intercept we have to subsitute the given point
-3 = -(2) + b
-3 = -2 + b
b = -1

Answer: B. 2</h3>
How I got that answer:
The data set for Marcus is
2, 3, 5, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 10, 10
The five number summary is
- min = 2
- Q1 = 6
- median = 7
- Q3 = 8
- max = 10
So the interquartile range (IQR) is
IQR = Q3 - Q1
IQR = 8 - 6
IQR = 2
