Equation that fits best in data is .Although there are no options , kindly match this equation to options available!
<u>Step-by-step explanation:</u>
We are given a graph with y & x-axis , with 4 points given and best fit for data can be found out by joining points . On joining points , we see that best fit is a line . General equation of a line is : ,
where m = slope of line & c = intercept.
Let's calculate slope m :
Consider any two given points , let's have ( 4,0) & (3,30) :
Slope = m
⇒ m =
⇒ m =
⇒ m =
So , equation now becomes :
⇒
at x = 0 we have y = 4
Therefore, equation that fits best in data is .Although there are no options , kindly match this equation to options available!
