# Write an equation for a line given two points

To avoid this vicious circle certain concepts must be taken as primitive concepts; terms which are given no definition. When the line concept is a primitive, the behaviour and properties of lines are dictated by the axioms which they must satisfy. In a non-axiomatic or simplified axiomatic treatment of geometry, the concept of a primitive notion may be too abstract to be dealt with. Find the slope and the y-intercept of the line. This example is written in function notation, but is still linear. As shown above, you can still read off the slope and intercept from this way of writing it. We can get down to business and answer our question of what are the slope and y-intercept. In this form, the slope is m, which is the number in front of x.

In our problem, that would have to be 2. In this form, the y-intercept is b, which is the constant. In our problem, that would be The answer is the slope is 2 and the y-intercept is Note how we do not have a y. This type of linear equation was shown in Tutorial If you said vertical, you are correct.

The graph would look like this: Note that all the x values on this graph are 5. Well you know that having a 0 in the denominator is a big no, no. This means the slope is undefined. As shown above, whenever you have a vertical line your slope is undefined.

Looking at the graph, you can see that this graph never crosses the y-axis, therefore there is no y-intercept either. Another way to look at this is the x value has to be 0 when looking for the y-intercept and in this problem x is always 5.

## Steps For Writing Equations Given Two Points

So, for all our efforts on this problem, we find that the slope is undefined and the y-intercept does not exist.The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept..

If you know the slope (m) any y-intercept (b) of a line, this page will show you how to find the equation of the line. Does anybody know an equation or approximation for calculating the azimuth as a function of latitudes and longitudes of both the points.

For example I have Princeton, NJ is at ° N, Learn how to find the equation of the line that goes through the points (-1, 6) and (5, -4). Equation of a Line Given Slope and a Point. How to write the equation. Step One: State the issue.
