How many times does 8 go into 285?
We need to put these equations into y=mx+b format.
5x-3y=-6
-3y=-5x-6. (take 5x from both sides)
y=5/3 x +2 ( divide both sides by -3)
The slope is 5/3
3x+5y=-20
5y= -3x -20 (subtract 3x from both sides)
y=-3/5x -4 (divide both sides by 5)
The slope is -3/5
The slopes of perpendicular lines are the opposite (+/-) reciprocal. We have 5/3 and -3/5. This shows they are perpendicular.

Answer:
$(4/3)X
Step-by-step explanation:
Working 12 hours, Samia gets paid for the first 8 hours ...
8 · ($X) = $8X
For the remaining 4 hours, she is paid ...
4 · ($2X) = $8X
Then for 12 hours, she is paid a total of ...
$8X +$8X = $16X
Her average hourly pay is then ...
total pay / total hours = $16X/12 = $(4/3)X . . . average hourly pay
