f(x) = mx + b
m = slope = -5
f(2) = 10 = (-5)(2) + b
b = 10 + 10 = 20
Ans. m=-5, b = 20
Answer:
B) 700 mg to 740 mg.
Step-by-step explanation:
Because the mean is the average of a data set, it means that there must be data above and below this value.
If the average is 720 mg, in the range there must be values that exceed this value and others that are below this.
We will analyze each of the options.
A) 740 mg to 780 mg.
There are values above 720, but not below 720.
B) 700 mg to 740 mg.
In this case, there are values below and above 720.
C) 680 mg to 720 mg.
There are only values below 720.
D) 660 mg to 700 mg.
There are only values below 720.
E) 620 mg to 660 mg.
There are only values below 720.
Therefore the answer is B) 700 mg to 740 mg. Since it fulfills the premise that guarantees the mean.

Step-by-step explanation:
Given
Points on line 
The standard form of an equation is 
Using the two-point form of a line
Answer:
See attached graph.
Step-by-step explanation:
To graph the equation, use its form y = mx+b to guide you.
Since y = 7x + 1 then m = 7 and b=1. Start on the y-axis at 1. Plot this points. From this point go up 7 units and over 1 units. Plot this point (1,8). Connect the points.
