**Example
Problem 2**

Find the equation of a line with a slope equal to 3 that passes through the point ( 1, 2 ). |

**Solution 2**

Basically, you can use one of two
approaches. The first approach is to use the point-slope
formula and the second is to use the slope-intercept. To
illustrate this, we will do it both ways.
To use the point-slope form in determining the
equation of the line, we simply plug in the values of
To use the slope-intercept form in determining the
equation of the line, we simply plug in the values of
Once we have obtained
Now that we have solved the problem using both the
As you can see, both approaches will give you the correct equation of the line. The only difference is which form it is in. |
