Answer:
x1 y1 x2 y2
(2 5) (-1 -4)
slope m = (y2-y1)/(x2-x1)
( -4 -5 )/( -1 -2 )
( -1/ -1 )
m= -1/-1
Step-by-step explanation:

The discount is $2. 2/20 is 0.1 or 1/10 which as a percentage would be 10%. The discount of $2 is <u><em>10%</em></u> off.
A is equal to 1100 miles
B is equal to 3300 miles
You take 1650 and divide by 3 which is 550, that is 1 hour is equal to 550 miles.
Answer: -3
-3(0)-1=-1
-3(-4)-1=11
-3(-6)-1=17
I hope this is good enough:
A random variable can be either discrete or continuous. It is discrete it can assume only a finite number of values, or a countable infinity of values at most.
It is continuous if it can assume values in an interval, or in general, an uncountable infinity of values.
That being said, we have:
Option A is a discrete random variable, because the number of heads in 5 throws can be 0, 1, 2, 3, 4 or 5. So, we have finitely many possible values.
Option B is a discrete random variable, because the number you roll on a die is either1, 2, 3, 4, 5 or 6. So, we have finitely many possible values.
Option C is a discrete random variable, because if there are n students in a class, the number of boys is an integer between 0 and n. So, we have finitely many possible values.
Option D is finally a continuous random variable, because the height of a 10-year-old can be any number (in a suitable range of course).
