The linear function f(x) = 0.9x + 79 represents the average test score in your math class, where x is the number of the test taken. the linear function g(x) represents the average test score in your science class, where x is the number of the test taken.
x g(x)
1 78
2 79
3 80
part a: determine the test average for your math class after completing test 2. (2 points)
part b: determine the test average for your science class after completing test 2. (2 points)
part c: which class had a higher average after completing test 4? show work to support your answer. (6 points)

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
