Given parameters:
Equation of the line is y = -
+ 8
Unknown:
Slope of line parallel to this line = ?
Slope of line perpendicular = ?
Solution:
A line parallel to this line will have the same slope with it.
A line perpendicular will have the negative inverse of this slope;
Slope of line = - 
Slope of line parallel to this line =
Slope of line perpendicular = negative inverse = -( -(
)) = 2
So, the slope of line parallel to this line is - 1/2 and that perpendicular is 2
Answer:
8399
Step-by-step explanation:
78*100=7800
58*10=580
7800+580+19=8399
First plug in the equations, then simplify/cancel out terms until you get the answer
