The x and y coordinates
Substitute the coordinates of the point into the equation of the line. If the result is true, then the point is on the line.
Subtract the equation of one line from the equation of the other
Substitute the coordinates of the point into the equation of the line. If the equation is still valid then the point is on the line; if not then it is not.
(y -y1)=(x -x1)(y2 -y1)/(x2 -x1) defines the line containing coordinates (x1,y1) and (x2.y2).
By substitution
if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form
Yes, I'm confident of that.

The x and y coordinates
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.

True.
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
