Using the given information in the point-slope form of the equation of a line, derive an equation for the given line.



where are the coordinates of the given point and is the given slope.

For this exercise, you need not simplify or rearrange the equation. Simply making the coordinate and slope substitutions will suffice.

Once you have derived the equation, substitute the coordinate values of the three given points into the equation. If the result is a true statement, then the point is on the line. If the result is false, the point is not on the line.
