Write an equation for the line that passes through (0, -9) and (3, 0).

1 answer:

8 0

First find the slope of the line:-

= (0- - 9) / (3 - 0) = 9/3 = 3

Now use the point slope form of the equation to plug in the point (3,0):-
y - y1 = 3(x - x1)
y1 = 0 and x1 = 3:-
y - 0 = 3(x - 3)

y = 3x - 9 is the answer Its D.

grandymaker [24]

The equation for volume is V= (pi)(R^2)xH
For Pi use 3.14
So switch the variables for the numbers that we know
V= (3.14)(3^2)x4
3^2= 9
3.14 x 9= 28.26
28.26x9 = 113.04
113.04 to the nearest tenth would be 113.
