With even just two points, you can find the equation of a line in slope-intercept form.
Slope-intercept form:  where
 where  is the slope and
 is the slope and  is the y-intercept
 is the y-intercept
<u>1) Solve for the slope (</u> <u>)</u>
<u>)</u>
The equation to solve for the slope is  when the two points are
 when the two points are  and
 and  . Plug the coordinates of these points into the equation and solve for
. Plug the coordinates of these points into the equation and solve for  .
.
Then, plug  into
 into  .
.
<u>1) Solve for the y-intercept (</u> <u>)</u>
<u>)</u>
Then, take any of the given points and plug it into  along with the slope. Isolate
 along with the slope. Isolate  to get the y-intercept. Then, plug both m and b back into
 to get the y-intercept. Then, plug both m and b back into  to get your final equation.
 to get your final equation.

Answer:
82 kg
Step-by-step explanation:
To find the mean of a set of values, we must add them up and divide by the number of values.
Step 1, adding the values:

Step 2, dividing by the # of terms:
There are 9 terms in total.

To the nearest kilogram, we can round 81.556 into 82.
The mean mass of the 9 men was  kg.
 kg.

What we know:
we know that there are <u>75</u> chicks in the hen house, we also know that in all there are 108 chicks
What we need to find:
we need to find out how many chicks were outside
Answer equation:
108 - 75 = 33
