Answer:
<u><em>y = -(2/5)x+4</em></u>
Step-by-step explanation:
The 2 points are 0,4 and 5,2. If you want to find the equation, you need slope. slope = rise/run = -2/5.
y = mx + b. The b is the y intercept, so it's 4.
The equation is <u><em>y = -(2/5)x+4</em></u>
Yes there is actually a formula for this. This is an arithmetic progression with a common difference of 1.
The sum of terms can be solved by using the formula
S = (n/2) * (a1 + an)
where S is the sum of the terms
n is the number of terms
a1 is the first term
an is the last term
we can calculate the number of terms, n by using the formula
an = a1 + (n-1)*d
d is the common difference equal to 1
therefore n = 51
substituting to the first equation
S = 2805
The mean is the average.
To find the mean, you add up all the numbers, and then divide by the number of numbers.

4 because above the number 0 there is 4 dots :/ I don't have another explanation.
