Answer:
y = 4/3x -7
Step-by-step explanation:
The marked points differ in their y-values by +4, and their x-values by 3. The slope of the line is ...
m = rise/run = 4/3
There is a marked point on the y-axis at y = -7. This is the y-intercept. Then the desired equation is ...
y = mx +b . . . . . line with slope m and y-intercept b
y = 4/3x -7
Answer:
The percentage [regression line is unexplained] = 60.6%
Step-by-step explanation:
Given:
Coefficient of determination = 0.394
Find:
The percentage [regression line is unexplained]
Computation:
Coefficient of determination = 0.394
Coefficient of determination = 39.4%
The percentage [regression line is unexplained] = 100% - Coefficient of determination
The percentage [regression line is unexplained] = 100% - 39.4%
The percentage [regression line is unexplained] = 60.6%
