Okay First,
Start with the given equation <span>Subtract from both sides
Rearrange the equation
Divide both sides by
Break up the fraction
Reduce
Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is Since this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis
</span>
First one.
Its a straight line with a slope of 6.
A line with a slope of 6 has a form of:
So when 
, 
becomes 
and so on.
Hope this helps.
The plane has searched 12,950 hectares. the ratio between hectares to square miles is: 1 hectare is 2.471 acres
C.) 1600 pi cm3
When you do 10^2 you get 100 and you multiply that by the height so 16 and you get 1600.
