600-120 = 480 480*15 = 7200$ That means he spent 7200$ in 15 weeks and saved 1800$
The inscribed angle is half the measure of the intercepted arc:
142°/2 = 71°
When a line is given in the form

The slope of the line is m. So, in this case, the slope of
is -1.
Given a slope
, you find the slope of a perpendicular line
by imposing

So, if the given line has slope -1, a perpendicular line has slope
given by

and thus 
So, we want a line with slope 1 and passing through (9,2). Using the fomula

we get
