(a)
The slope-intercept form equation for the equation of the line of fit with the help of the following graph:
(a)
Answer to Problem 5PPS
The final slope intercept form equation is derived as
Explanation of Solution
Given:
Concept Used:
The slope intercept form equation is
Where;
Slope:
Y-intercept:
Calculation:
Consider,
Year since
Amount spent:
There are two points are given in the graph:
Now use any two points to calculate the slope intercept from equation:
Now, the slope intercept form equation is written as:
Now put the value of
So, the final slope intercept form equation is:
Conclusion:
Hence, slope-intercept form is derived with the help of the line of fit.
(b)
The amount which will be spend by the government for space and other technology the in the year
(b)
