Answer:
-51/82.
Explanation:
Given two points (x1,y1)=(2,21) and (x2,y2)=(84,-30), we find the slope using the formula below:

Substitute the given points:

The slope of the line that passes through the given points is -51/82.
Answer:
a) The mass is released at t = 0 when h is minimum. Half a cycle later h reaches its maximum and another half a cycle it reaches its minimum again. Hence over one cycle, h varies with t as follows:
b) According to the graph obtained in part a), h(t) could be modeled by a cosine function shifted (translated) vertically up and horizontally to the right. Hence
