In this lesson, Naomi teaches how to find the equation of a line when given two points. The first step is to find the slope of the equation using the slope formula. Then, using either one of the points with the slope, we can plug them into the point slope formula to get an equation for the line. Naomi provides an example of a problem containing fractions and simplifies the expression to get the slope. Finally, she uses the point slope formula with the second point to find the final equation.
This is an example of how to find the equation of a line through two points, when the two points contain fractions, with the point slope formula.
