4
5
6
7

Length BC : 5 units.

Step-by-step explanation:

Given  : Line BC with B (  -3 ,-2) and C ( 0 ,2) .

To find : What is the length of segment BC.

Solution : We have given  Line BC with B (  -3 ,-2) and C ( 0 ,2) .

Length of BC  mean distance between the point B and C.

Distance formula  : .

.

Plug the values in above formula.

Length BC : .

Length BC : .

Length BC : .

Length BC : .

Length BC : .

Length BC : 5 units.

Therefore, Length BC : 5 units.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
