Question

"if the regression equation is equal to y=19.6 - 52.2x, then 19.6 is the ______ while -52.2 is the ____ of the regression line."

Answer 1

Lets analyze this question as follows:

The equation of a line is given by :

y = mx + c

Where :

m = The slope or the gradient of the line.

c = The y intercept of the line.

From this we can answer the question.

In our case :

m = -12.2

c = 19.6

Therefore:

19.6 = y intercept

-52.2 = Gradient
