If a regression line has a y-intercept of 6.75 and a slope of 1.25, then when x = 2 the actual value of y is:

The term “Regression Line” refers to the statistical technique which is used to model the relationship between two variables.

The actual value of y is 9.25.

Given

If a regression line has a y-intercept of 6.75 and a slope of 1.25.

The term “Regression Line” refers to the statistical technique which is used to model the relationship between two variables.

The standard form of the regression line is;

Where m is the slope of the line and c is the y-intercept of the line.

Therefore.,

The actual value of y is;

Hence, the actual value of y is 9.25.

Question is describing about a regression line which has a y-intercept of 6.75 and a slope of 1.25.

y-intercept is represented by letter "b" in formula y=mx+b

so b=6.75

slope is represented by letter "m" in formula y=mx+b

so m=1.25

Now we have to find the y-value when x = 2.

To find that we just need to plug given values x=2, b=6.75 and m=1.25 into formula y=mx+b. We get:

y=1.25*2+6.75

y=2.5+6.75

y=9.25

Hence final answer is y=9.25.
