Answer:
Non-Proportional
Step-by-step explanation:
It goes through (0,0) ; (1,1) ; so it should go through (2,2) ; but it goes through (4,2). Therefore it is not proportional.

Hey there! :)
Answer:
-1/2.
Step-by-step explanation:
For a line to be perpendicular, the slope must be the negative reciprocal of the original. In this instance:
A line perpendicular to y = 2x + 7 must contain a slope that is the negative reciprocal of 2.
The negative reciprocal of 2 is -1/2. This is the slope of a perpendicular line.
To find the mean transaction amount. We need to understand mean first.
Mean (or average) is a number that expresses the central value in a set of data, which is calculated by dividing the sum of the values in the set by their number of values.
Here, the transactions shown are
$250, -$60, -$94, $300, and -$186. So there are 5 transactions.
Now mean transaction amount is given by:
So, the mean transaction amount over 5 transactions is $42.00.
