After drawing the line y = 2x − 1 and marking the point a = (−2, 7), kendall is trying to decide which point on the line is closest to a. the point p = (3, 5) looks promising. to check that p really is the point on y = 2x − 1 that is closest to a, what should kendall do? is p closest to a?

Step-by-step explanation:

Having drawn the line, Kendall must verify that the point P belongs to the line y = 2x-1 and then calculate the distance between A-P  and verify if it is the closest to A or there is another one of the line

Having the point P(3,5) substitue x to verify y

y=2*(3)-1=6-1=5 (3,5)

Now if the angle formed by A and P is 90º it means that it is the closest point, otherwise that point must be found

and we found the distance PQ and QA

; ,

be the APQ triangle we must find <APQ through the cosine law (graph 2).
