value of x is and value of y is
Step-by-step explanation:
We need to find Which expression could be substituted for y in the second equation to find the value of x
The given equations are:
For putting value of y in second equation, we will find from equation 1
From equation 1:
Putting value of y i.e y=10+2x in equation (2) to find value of x
So, now finding value of y by putting value of x= -29/4 in eq(1)
So, value of x is and value of y is

Given:
The data points are:
(1, 0), (2, 3), (3,1), (4,4), (5,5)
To find:
The equation of best fit line in the form of and then find the value of b.
Solution:
The general form of best fit line is:
...(i)
Where, m is the slope of best fit line and b is the y-intercept of the line.
Using the graphing calculator, we get the equation for the best fit line and the equation is
...(ii)
On comparing (i) and (ii), we get
Therefore, the value of b is equal to -0.7.
