Answer:
Step-by-step explanation:
A line in 2-dimensional space has the following general equation:
Where m is the slope of the line, and b just a number
the slope can be obtaine using th following formula:
The point 2 is the one with the smallest value for x, that is (-10,-7) and the Point 1 is any other that belongs to the line, in this case, (-5,-9)
Resulting that
To find the other term we can use any other point, I prefer us the first one so...
We have the following equation:
Resulting that b=18
I just have to eval the point (-10,-7) in the equation stated at the beginning knowin that m was calculated previously.
Step-by-step explanation:
y=mx+b (m is the slope, b is the y-intercept)
To come with sope choose two points from the graph (6,20), (4,30)
Then
m=(Y2-Y1)/(X2-X1) =(4-6)/(30-20)=-1/5
b= 50 (y-intercept)
SO y=-1/5x-50
I hope this helps

Answer:
$126,000
Step-by-step explanation:
16% of 150,000 is 24,000
150,000-24,000=126,000
