Part 1.

The slope is found by the change in Y over the change in X.

In the picture they are finding the difference between the X and Y of each point. They have x1 - y1 over x2-y2, when it should be y2-y1 / x2 - x1.

Part 2:

Slope = Change in Y over change in X:

(4 - 6) / (0 - -2) = -2 / 2 = -1

Slope = -1

Using the point (0,4) tells you the Y-intercept, which is the Y value when x is 0. The Y intercept is added to the slope when writing the equation of a line in point slope form.

The equation is y = -x +4

Part 3:

Find two points on the line by replacing X with 0 and solving for Y and then replace Y with 0 and solve for X. This gives you the X and Y intercepts. Once you have those two points, put them on a graph and then draw a straight line through both dots.

Nuclear Power is a perfect example of exponential relations. Canada produces over half of its electricity using nuclear reactors

mario62 [17]

Solution :

Nuclear fission is exponential. With uranium atoms arranged properly it is possible to have the fission effect and cause more and more uranium nuclei to fission. This is known as chain reaction and a number of uranium atoms are fission together to increase exponentially.

Canada, for example produces electricity using the process of fission process in its nuclear reactors.

But one of the problems with nuclear reactors is its disposal of the nuclear waste. The nuclear waste includes the used reactor fuel, uranium mill tailings and other radioactive wastes. They remain radioactive and are dangerous for the human health.

A). The long term nuclear waste are stored in deep excavations and covered with rocks and mud so that the harmful radioactive materials does not escape from them. They are also stored in some high density and thick cylinders and remained isolated in the dump yard from the people and nature.

B). Canada has a high source of renewable sources of energy. This is a clean source of energy and Canada can make best use of it. Most of the energy requirement of Canada can be taken care off by using wind energy. Canada is planning to set up wind energy mills in most of its part and generate electricity from it.

Canada has also installed several solar power projects which is clean and can help the people to use this solar energy to produce electricity.
