How do you write the equation in point slope form given (2, 5) and (–1, 8)?
See a solution process below:
First, we need to determine the slope of the line. The slope can be found by using the formula:
Substituting the values from the points in the problem gives:
The point-slope formula states:
We can substitute the slope we calculated and the values from the first point in the problem giving:
We can also substitute the slope we calculated and the values from the second point in the problem giving:
