Question

complete the activity: i) show that points P (-2, 3), Q (1, 2), R (4, 1) are collinear. sollution : P (-2, 3), Q (1, 2) and R (4, 1) are the given points. X1 = -2, X2 = 1, X3 = 4, Y1 = 3, Y2 = 2, Y3 = 1 slope of line PQ = Y2 - Y1/ X2 - X1 = 2 - ......... / 1 - ......... = -1 / .......... slope of line QR = Y2 - Y1 / X2 - X1 = .......... - 2 / 4 - ........... = -........... / -3 therefore slope of line PQ and line QR are ............. therefore Points P, Q, R are .............

please give answer fast​

Answer 1

Answer:

The given points are collinear.

Explanation:

First of all you gotta calculate the slope of line PQ and QR . If the slopes are equal then the points are collinear.
