Given:
The table of values.
To find:
The least-squares regression line for the data set in the table by using the desmos graphing calculator.
Solution:
The general form of least-squares regression line is:
...(i)
Where, m is the slope and b is the y-intercept.
By using the desmos graphing calculator, we get

Substitute these values in (i).


Therefore, the correct option is A.
D
A nonproportional relationship is a linear line that doesn’t go through the origin.
y=3x+0 does go through the origin because the y-intercept (the b) is 0
Y=x/4 also has a y-intercept of 0
Y=7x also has a y-intercept of 0.
y=2/5x+7 does not go through the origin because the line passes the y-axis at (0,7) which is the y-intercept.
Answer:
b = 131
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
b+49 = 180
Subtract 49 from each side
b = 180-49
b =131
