I'd say the answer to the first question is D) 0 to 4 with intervals of 0.2.
Because, you can't just have 1 to 4, as some of the numbers are less than 1. Of course you can't have 2 to 5 either. And intervals of 2 would be too messy.
For the second question:
I believe the answer is A. Because it's obvious that there IS one outlier, and it looks like there are two clusters.
So, the answers are: A) and D).
Answer:
Both lines are perpendicular
Step-by-step explanation:
We want to determine the relationship between the two lines.
The best thing to do is to calculate the slope of the two lines;
Mathematically;
Slope = y2-y1/x2-x1
For PQ; slope will be;
(-3-17)/(1-(-4) =-20/5 = -4
For RS
slope = (4-3)/(-5-(-9)) = 1/4
Now we have -4 and 1/4 as slopes
The product of both is 1/4 * -4 = -1
When two lines are perpendicular, the product of their slopes is -1
We can conclude that both lines are perpendicular to one another
