Question 236963
<font face="Garamond" size="+2">


Step 1.  Select any two pairs of *[tex \Large x] and *[tex \Large y] values, and then substitute these values into the formula for the slope and do the arithmetic.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ m\ =\ \frac{y_1 - y_2}{x_1 - x_2}]


Step 2.  Select any of the coordinate pairs in your table and substitute *[tex \Large x] and *[tex \Large y] values and the calculated value of the slope from step 1 into the point-slope form of the equation of a line:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y - y_1 = m(x - x_1) ]


Check your answer by substituting the *[tex \Large x] and *[tex \Large y] values  of the three pairs NOT selected in step 2 into your derived equation.  Do the arithmetic and verify that you have a true statement in each case.
