Answer:
C. The slope of the function is -2 and the y-intercept is 4.
Explanation:
The y-intercept is the point when x = 0. On the table when x is 0, y is 4.
The slope of the function is -2 because the y value is going down by 2 for each +1 of x.
x │ y
-2 │ 8
0 │ 4
↓ +1 ↓ -2
1 │ 2
↓ +1 ↓ -2
2 │ 0

Step-by-step explanation:
In any right triangle, the following is true:
The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)
The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)
The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)
Thus,
Givens
Start = S = - 700
# Correct = C = 8
Value Correct = VC = 400
# Incorrect =I = 9
Value Incorrect =VI = - 600
Equation
Score = S + C*VC + I*VI Substitute
Solve
Score = -700 + 8*400 + 9(-600)
Score = -700 + 3200 - 5400
Score = - 700 - 2200
Score = - 2900 <<<<< Answer

If you're supposed to find x that satisfies this equation, this is a relatively challenging problem.
One way to approximate the solution would be to plot y = (3/2)x + 7/2 and y=2^x carefully on the same set of axes. Try to read off the x- and y-values at the single point where these two graphs intersect. (x, y) would be your solution.
I did this graphically on my calculator and found that the point of intersection is (3,8).
To check, determine whether y = 2^x is true when x = 3 and y = 8, and also check whether y = (3/2)x + 7/2 is true for the same x and y values.
