Perpendicular means that the slopes are negartive inverses, aka
slope1 times slope2=-1
y=mx+b
slope=m
y=-1/2x-2
slope=-1/2
we need to find negative inverse
-1/2 times what=-1
answer is 2
y=2x+b
input the point (2,-2) to find b
(x,y)
(2,-2)
-2=2(2)+b
-2=4+b
minus 4 from both sides
-6=b
y=2x-6
the equtaion is y=2x-6
x is the base and 4 is the exponent
Answer:
Average mean salary 
Step-by-step explanation:
We have been given year and respective salaries in each year.
1960 $4,995
1970 $8,626
1980 $15,970
1990 $31,367
2000 $41,807
2010 $55,202
Now we nee do to determine the average mean salary for the six decades, 1960 – 2010.
So we just need to add all those six salaries and divide that sum by 6 to find the average mean salary.
Average mean salary 
Average mean salary 
Average mean salary 
Hence final answer is approx:
Average mean salary
