Answer:
[tex]\left(1, 2\right)[/tex], [tex]\left(\frac{7}{2}, 2\right)[/tex] [tex]and \left(6, 2\right)[/tex].
Step-by-step explanation:
Any point in coordinate system has a x-coordinate and a y-coordinate. In coordinate system any point p will be represented as [tex]p(x-coordinate, y-coordinate)[/tex].
Any three points in coordinate system will lie on the same horizontal line if they have same values for their y-coordinate. While the values for x-coordinate for these points should be different.
