<u>Answer:</u>
-2/3
<u>Step-by-step explanation:</u>
We are to find the slope of a line which is perpendicular of a line with an equation 
.
We know that the slope of line which is perpendicular to another line is the negative reciprocal of that perpendicular line.
So writing the given equation of a line in the slope intercept form:
---> 
Here the slope of this line is 
so the slope of a line which is perpendicular to the given line will be 
.
Answer:
2.1
Step-by-step explanation:
Use the equation
Sum of elements = average x number of elements
sum = (6)(4)
sum = 24
Add up the numbers we know: 3.4 + 10.7 + 7.8 = 21.9
24 - 21.9 = 2.1
This means the fourth number is 2.1
