Using the regression formula with a slope = 2000 and intercept = 15000, what would the predicted income be for someone who has 16 years of education.
Y-3=1/2(x+2)
To find the y-intercept, we must first get the equation in slope intercept form. Start off by distributing 1/2 into the parentheses.
y-3= 1/2x+1
Add 3 to both sides
y= 1/2x+4
The slope is whatever is in front of x, in this case, 1/2. The y-intercept is the number after that which would be 4
Answer:
C
Step-by-step explanation:
Mean is the average. To find mean, add all the numbers in a data set, then divide by the number of values.
Example: 1,2,3,4,5
Mean: 1+2+3+4+5= 15
Number of values: 5
15/5 = 3
Mean is 3

Answer:
The relationship is proportional.
The relationship is linear.
The equation of the line is y = –3x.
Step-by-step explanation:
The line in the question passes through origin and (4,-12).
The rate of change of the line is

The rate of change of the line or slope of the line is -3
Equation of the line is given by

This means that the relationship is linear.
If we take any value of x then there will be only one value of y this means that the relationship is proportional.
So the following statements are true
The relationship is proportional.
The relationship is linear.
The equation of the line is y = –3x.
