Question

12. The points (1,1),(-2, 7) and (3,-3) are​

Answer 1

Answer:

collinear points

Step-by-step explanation:

Three or more points that lie on the same line are collinear points.

m = $(y_{2} - y_{1}) / (x_{2} - x_{1})$

~~~~~~~~~~

Find slope of line passing through (1, 1) and (- 2, 7)

m = $\frac{7-1}{-2-1}$ = - 2  

Find slope of line passing through (1, 1) and (3, - 3)

$m=\frac{-3-1}{3-1} = - 2$

The points (1, 1), (- 2, 7), (3, - 3) are collinear.
