make a scatter plot using the given points (5,7) (-1,6)(0,-6) (-3,2)
You want to find the slope that represents the best the situation right?
yes it give multiple choices for the situtation zeep
Ok good, are you familiar with Mayer's method?
no
What about the rectangle method (approximation method)?
its greek to me
Okay let me explain Mayer's method, it's really easy easy.
First of all, order your points from the lowest value of x to the highest value of x.
(-3,2) (-1,6) (0,-6) (5,7) Now split it in half so both part contains the same number of points. *splits* (-3,2) (-1,6) _________ (0,-6) (5,7) Voila!
got it zepp
Good!, Now calculate the average of each section \((-3+-1)/2=(-3-1)/2=(-4)/2=-2\) \((6-2)/2=4/2=2\) Average point of the first part is \((-2,2)\) \((5+0)/2=5/2=2.5\) \((7--6)/2=13/2=6.5\) Average point of the second part is \((2.5,6.5)\) Is it understandable?
Now you have two points \((-2,2)\) and \((2.5,6.5)\) and you are asked to find the slope, you know what to next :)
