How do you find the equation of the line that passes through the points (7,3) and (2,5)?
To find the line passing through these two points we will use the point-slope formula. However, first we must determine the slope.
The slope can be found by using the formula:
For our problem we can substitute and find the slope as:
Now we can use the point-slope formula. The point-slope formula states:
Substituting the slope we calculated and one of the points we were given.
or, converting to slope-intercept form:
