The graph of a line passes through the points (0, -2) and (6, 0). What is the equation of the line? 1. y = -2x + 6
densk [106]

Answer:

The Answer is: y = 1/3x - 2

Step-by-step explanation:

Giving points: (0, -2) and (6, 0).

First find the slope:

m = y - y1/(x - x1)

m = -2 - 0/0 - 6

m = -2/-6 = 1/3

Use the point slope form of the equation with point (0, -2) and solve for y:

y - y1 = m(x - x1)

y - (-2) = 1/3(x - 0)

y + 2 = 1/3x

y = 1/3x - 2

Hope this helps! Have an Awesome day!! :-)

A gas company’s delivery truck has a cylindrical tank that is 16 feet in diameter and 48 feet long. How much gas can fit in the
Nady [450]
Answer: V=9651 ft^3

Explanation: This is a volume question and the formula for volume of a cylinder is πr^2h.

The radius is the diameter divided by 2, which is 8.

We can put the equation in terms of π by doing π*(8^2*48)=3072π.

Solving this gives us about 9650.972632, which you can round to get 9651.
