We can write the equation for the line that connects the points in .
represents the and
is a point on the line. To write the equation, we'll first need to determine the slope. To do this, we will use the and our two points.
The slope of the line is
We can now substitute the value for
in the formula.
We should now write two
equations of the line. Thus, we will use both our points,
and substitute them for
to form two equations.
Any point that lies on the line can be used to write an equation in point-slope form. Our answer will be
