Ron-Jon and Lena-Jon attempted to write the equation of the line that passes through the points
To determine who is correct, we will and compare it with their answers. Let's write the equation in .
is the and
is the . We will find the slope using the .
Now that we know that the slope of the line is
we can partially write its equation.
To find the
we can substitute either given point into the above equation. Let's use
We can now write the complete equation of the line.
We obtained the same equation as Lena-Jon, and thus she is correct. Probably, Ron-Jon substituted the points in the wrong order when finding the slope.
