Answer:

Equation of a line has form of y = ax + b

This line passes (-8, 8) and (1, 10), then:

-8 = -8 x a + b

10 = a + b

Subtract 2nd equation to 1st equation, then:

18 = 9 x a

=> a = 2

=> b = 10 - 2 = 8

=> y = 2x + 8

Hope this helps!

A set of n = 15 pairs of X and Y scores has SSX = 10, SSY = 40, and SP = 30. What is the slope for the regression equation for p

Mumz [18]

Answer:

Step-by-step explanation:

We have given $SS_X=10$ , $SS_Y=40$ and SP =30

We have to find the slope for regression on Y from X

The slope on Y from X is given by $b_{yx}=\frac{SP}{SS_X}$

As we have given the value of SP =30 and value of $SS_X=10$

So slope for regression will be $b_{yx}=\frac{30}{10}=3$
