Question 240419
<font face="Garamond" size="+2">


Since "corridents" is not a word that has meaning in the English language, I will allow myself to infer from the rest of your question (if indeed it is a question, since there is no question mark anywhere to be seen) that you meant to say "coordinates."


Use the formula for the slope:


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


Plug in the values you were given:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 5 = \frac{6 - r}{1 - 4} ]


Now all you need to do is solve for *[tex \LARGE r]
