What is the equation in point-slope form and slope intercept form for the line given (–1, –3) and (4, 1)?
Given two points
the slope is
For the given points
Now that we have the slope we can use either of the given points to write a slope-point form for the equation:
The slope intercept form is
Working with the previously developed slope-point form:
We obtain the slope-intercept form:
