Answer:
Step-by-step explanation:
It is stated that a function rule takes an input, and converts it into an output, y, by decreasing twice the input by 4.
Let 'x' be the number
Decreasing twice the number 'x' by 4 = 2x-4
Now,
Given the input x = 5
As the output will decrease twice the input (x=5) by 4
Thus, the output = 2(5)-4 = 10-4 = 6
Therefore,
If the line passes through the points
and
then the slope of the line can be determined as

Then the equation of the line is

Answer: correct choice is B
The percent error is 25 %
<em><u>Solution:</u></em>
Given that it is estimated that there are 50 students in the seventh grade class, but there are actually 40
<em><u>To find: percent error</u></em>
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%
<em><u>The formula for percent error is given as:</u></em>

Here, exact value = 40 and approximate value or estimated value = 50
Substituting the values in above formula,

Thus the percent error is 25 %
10.20*8= 81.60
10.20*.5= 5.10
add
81.60+5.10= 86.70
