The required equation is:

Step-by-step explanation:

We have x = Distance of goal posts

y = field Goals made

The data given is:

x       y

20     9

25      6

30       7

35       4

40       1

45        2

50        1

We need to find the regression equation y = bx + a

Where

Sum of all values of x = 245

Sum of all values of y = 30

Now, calculating mean using formula:

Mean of x (Mₓ) = 35

Mean of y () = 4.28

Sum of squares (SSₓ) = 700

Sum of products (SP) = -190

Now, finding b:

Now, finding a:

So, the required equation is:

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
