Use slopes to determine if the triangle whose vertices are left parenthesis negative 4 comma 4 right parenthesis(−4,4), left parenthesis 1 comma 5 right parenthesis(1,5), and left parenthesis 2 comma 0 right parenthesis(2,0) is a right triangle. find the slope for the side of the triangle between the vertices left parenthesis negative 4 comma 4 right parenthesis(−4,4) and left parenthesis 1 comma 5 right parenthesis(1,5). mequals= one fifth 1 5 (type an integer or a simplified fraction.) find the slope for the side of the triangle between the vertices left parenthesis 1 comma 5 right parenthesis(1,5) and left parenthesis 2 comma 0 right parenthesis(2,0). mequals= negative 5−5 (type an integer or a simplified fraction.) find the slope for the side of the triangle between the vertices left parenthesis negative 4 comma 4 right parenthesis(−4,4) and left parenthesis 2 comma 0 right parenthesis(2,0). mequals= negative two thirds− 2 3 (type an integer or a simplified fraction.) is the triangle a right triangle?
