Answer:
s = -2400t + 17400
Step-by-step explanation:
Let's say t is the x value on a coordinate plane, and s is the y. Then, we have the points (0, 17400) and (6, 3000). The slope of these is 14400/-6 or -2400.
Now we just have the equation y = -2400x + b, and from the point (0, 17400) we can find that b is 17400. So, we have y = -2400x + 17400. Convert these back into t and s and you get your answer, s = -2400t + 17400.
What is being asked here? Are they asking for the passing grade or the total with all the other 90 points added? I think it is A, 90%
