Answer:

Step-by-step explanation:
To find the slope of the equation use
.
So,
=
. Now we can use our slope and any of the two points to write in point-slope form, which is
. Using the point (7,-6), the formula will give
.
To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.
Answer:
if the stone makes 150 revolution per minute, the tension force of the string on the stone is
