Answer:
the amplitude would be 2
Step-by-step explanation:
as much as I would like to, I'm not really the best at explaining things
The y-intercept of the line is (0, 12/7).
In the slope-intercept form, y = mx + b:
m = slope
b = y-intercept
The y-intercept is the point on the line where it crosses the y-axis, and has coordinates of (0, b). It is also the value of y when x = 0.
In the slope-intercept form, the value of b is the y-coordinate of the y-intercept, (0, b).
Therefore, the y-intercept = (0, 12/7).

so the nth term is really the 10th term, and we know that's 57, thus

so, that's the common difference... .so you'd surely know what the 3rd term is, notice the first one is 102.
Answer:
its A!!! :) good luck with the rest of your assignment!
