The table shows some values for the function f. If f is a linear function, what is the value of a+b?

a24
b36
c48
d72
eit cannot be determined from the information given.

x f(x)

0 a
1 24
2 b

The Answer is c48. How did they arrive at that answer?????????

The distance from a to 24 is the same as the distance from 24 to b.

So, 24-a = b-24
rearrange the terms to solve for
a+b = you do it.

I guess I do 24+24=48 right?
