Well if Abby is twice the age of her bother and her brother is 9 then she is going to be 18 because 9x2=18, then it says that she is half her dads age so all you have to do is add 18+18 which equals 36

Answer: A

Step-by-step explanation: So, first of all, this is a linear graph, which is represented by the equation y = mx + b.

b = y-intercept. The y-intercept is the point in which the line crosses the y axis. Assuming this graph has units that go up by 1, the y- intercept for this line is 2, which eliminates choices B and C.

This graph is going down, which means it is negative, so the format should be -mx + b, which is answer choice A. Hope this helps! :)
