If l is parallel to m, what is the relationship between 3 and 7?

a.
they are congruent because they are alternate external angles.
b.
they are congruent because they are corresponding angles.
c.
they are supplementary because they are corresponding angles.
d.
they are supplementary because they are alternate internal angles.

B.

Step-by-step explanation:

they are correseponding angles so that means that they aer congruent because the lines are parallel

  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.
