Drum role please..... it’s 7
Remark
The general equation for the point slope form is
(y - h) = slope(x - k)
<em><u>Givens</u></em>
given point = (5,7) from which
h = 7
k = 5
slope = m = - 13
Equation
(y - 7) = -13(x - 5) Usually the equation is left like this.
360.
A general rule of thumb when dealing with questions like these is using the following equation:
(number of numbers) x (mean) = sum of numbers
Proof/Example: 7, 10, 13
There are 3 numbers here and the mean is 10. Multiply them together and you will get 30, just as you will get 30 from adding them together.
In this case, there are 4 numbers and the mean is 90, so 4 x 90 = 360.
