B is the y intercept. It is where the point is on the y axis when x is 0(zero). Does that answer your question?

(0, -1) is the answer.  When you go 2 units up and 1 unit to the left from (1, -3), you will end up at the coordinates  (0, -1).

Which expression is equivalent to -4/7 - 8/9 + 4/7 - 9/8
olya-2409 [2.1K]

Answer:

<em>I misunderstood the question before, but here are two expressions equivalent to -4/7 - 8/9 + 4/7 - 9/8. </em>

71/72 + 70/72 +4/72

-1/7 - 3/7 - 5/9 - 3/9 + 2/7 +2/7 - 4/8 - 5/8

<em>Solved: -2 1/72</em>

Step-by-step explanation:

I could simply take the answer you get when combining all of the fractions, and I can make a new expression out of it. For example, I could use: 71/72+ 70/72+4/72. Or I could break apart all of the original fractions into smaller fractions. Example: -1/7 - 3/7 - 5/9 - 3/9 + 2/7 +2/7 - 4/8 - 5/8.

<em>To solve: Start by combining -4/7 and 4/7 to make 0, shortening your equation. Then continue by making the fractions remaining, 8/9 and -9/8, have a common denominator. To do this, we multiply -8/9 by 8, and -9/8 by 9. Then, we have -64/72 and -81/72. Then, we can combine the numerators of the fractions, as they have common denominators, and we get the fraction -145/72. We can then simplify this to -2 1/72.</em>

<em>Hope this helps!</em>

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:

3

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
