Answer:
C) They are perpendicular lines.
Step-by-step explanation:
We first need to find the slope of the graph of the lines passing through these points using:

The slope of the line that passes through (−12, 15) and (4, −5) is


The slope of the line going through (−8, −9) and (16, 21) is



The product of the two slopes is

Since

the two lines are perpendicular.
Answer:
60 mph
Step-by-step explanation:
Ms. Gayle drives 10 miles in just 10 minutes. To find out how fast she was going we need to turn the minutes into hours. There are 60 minutes in an hour, so we multiply the miles and minutes by 60.
Ms. Gayle drives 60 miles in an hour.
This means she is traveling at 60 mph.
I hope that this helps! :)
The picture isn't very clear
the answer would be 4.47
because every whole number is made out of 100 small parts.
So that would be like 400-53 which is 447 and then add the decimal point. That would make it 4.47
