Substitute the x coordinate into the equation for x and calculate y. If the formla gives the same y value as the coordinates, the point is on the line. If it is diffent, it is not on the line.
They must be the same identical line, otherwise it's impossible.
Collinear points are points that lie on the same line. Noncollinear points do not lie on the same line. Any two points are always collinear, i.e. forming a line. Three or more points can be collinear along a single line.Collinear points lies on the same straight line.
Yes, a line and a point can be on the same line. A point can be placed on a line. It will then be collinear.
If the point is not on the line, then no they are not collinear. But if that point is on the line, then they are collinear. Points on the same line are collinear. Points not on the same line are not collinear or non collinear.
Do you mean "Between two other points? If yes, when it lies on a straight line between both points that are farther away and on the same line.
The same line.
Since it is possible to draw a line through any two points, if there is a point that does not lie on the same line, it must be a third point.
You can either interpolate or extrapolate. Interpolate = find the target point on the line and draw vertical and horizontal lines to see what the X and Y values are. Extrapolate = extend line past it's known area and do the same.
