In the plane rectangular coordinate system, a (3, - 4), B (2, - 1), C (x, 2) if points a, B, C can form a triangle, then what conditions should x satisfy | Math enthusiast | Mathematical art

In the plane rectangular coordinate system, a (3, - 4), B (2, - 1), C (x, 2) if points a, B, C can form a triangle, then what conditions should x satisfy

You can draw a and B on the coordinate system, and then C is any point on the line y = 2
You can easily know that as long as a, B and C are not collinear, they can form a triangle
AB's equation, y = - 3x + 5, and the intersection of the line y = 2 is (1,2), so as long as X is not equal to 1
Hope to adopt
