Answer:

y= -1/5x - 10

Step-by-step explanation: the line has the form:  y=ax+b

the line goes through (-5,-9) --> -5a+b=-9

the line is perpendicular to y=5x+15 --> 5a=-1 --> a=-1/5

therefore (-5). (-1/5) + b = -9 --> b=10

HELP MEEEE PLEASE IM BAD WITH WORD PROBLEMS
patriot [66]

He worked 36 hours (9.57), and anything over that was over pay (14.36)

36 * 9.57 = 344.52

So, working his normal hours he got $344.52.

416.32 - 344.52 = 71.80

71.80/14.36 = 5

Therefore, he worked 5 hours of overtime.
