Explain how deductive reasoning is used to prove an argument.

3 0

Deductive reasoning is what is proven and what you already know for sure. Example: there are 2 ants. There is 1 ant next to the 2. There are 3 ants total. (Rules of addition)

So you don't have to solve any problems to use deductive reasoning, unlike inductive reasoning, which is not proven
Example of inductive reasoning: there are lots of girls in my class. So there are probably lots of girls in the other classes too. You don't know that for sure.

Using the slope and the y-intercept, graph the line represented by the following equation. Then select the correct graph. 3y = 2

Over [174]

First, let's write the given equation in slope-intercept form: y = mx + b

In slope-intercept form, the slope of the line is m, and the y-intercept is b. The slope is a measure of how steep the graph is at any point and is found by doing rise over run. This means the change in y values divided by the change in x values. Next, y-intercept is just where the graph crosses the y axis.

All we need to do to get the equation in slope-intercept form is to divide each term by 3. This will isolate the y.

$y= \frac{2}{3}x-2$

As you can see, the slope of the line is 2/3, and the y-intercept is -2.

To graph the line, plot a point at (0,-2). This is the point where the graph crosses the y axis. Then from that point, count up two and right 3. Plot a point here as well. Lastly, connect the two points with a straight line.

See attached picture for the graph.
