Answer:

First blank would be 25, Second blank would be 75.

Step-by-step explanation:

In order to figure out the blanks, we must figure out the original function first.

How do we do that?

-> we put in the points that we already have- in to equation:

    y = ax + b

If we put the 6, 10 in to x, y , we would get :

10 = 6a + b

If we put the 12, 20 in to x, y , we would get :

20 = 12a + b

because these share the "+b" they can be subtracted.

           10   = 6a + b

-           20 = 12a + b

--------------------------------------

and this would be :

-10 = -6a, a = 5/3.

we can partly complete the equation.

y = 5/3x + b, and by putting in the numbers, we can figure out that b=0.

The full equation have : y = 5/3x

now, put 15 and 45 in to the x and see what you get!

y=25, 75

Have a nice day :)
