Yes, when they are the coordinates of a straight line equation.
The equation ( y = 2x ) represents a straight line where the y-coordinate is twice the x-coordinate. To determine points that lie on this line, you can substitute the x-values into the equation and check if the resulting y-values match. For example, points like (1, 2), (2, 4), and (0, 0) all satisfy the equation and lie on the line.
3x-y=2 3x=y+2 y=3x-2 Some points: (0.-2)(1,1)(2.4)

To determine if line k contains points d and h, we would need specific information about the line's equation or the coordinates of points d and h. If both points lie on the line according to its equation, then yes, line k contains d and h. Otherwise, if either point does not satisfy the line's equation, then line k does not contain them.
Take any two points and form the equation for a straight line. If all the remaining points satisfy the equation, then they lie on astraight line. Else, they don't. Here's an example. Consider n points as P1(x1, y1), P2(x2, y2), ...., Pn(xn, yn). In order to determine if P1, P2, ..., Pn lie on a straight line, form the straight line equation with P1 and P2 as: y-y1= m * (x - x1), where the slope m = (y2-y1)/(x2-x1). Then try to satisfy this equation by the remaining points P3, P4, ..., Pn. That is, verify the following: Is y3-y1= m * (x3 - x1)? Is y4-y1= m * (x4 - x1)? ... Is yn-y1= m * (xn - x1)? If all of the above is true, then the points lie on a straight line.
All points whose x-coordinates equal their y-coordinates lie on the line described by the equation (y = x). This line passes through the origin (0, 0) and extends diagonally through the first and third quadrants of the Cartesian plane. Every point on this line has coordinates of the form ((a, a)), where (a) is any real number.
Any two points lie on the same line, since a line can be drawn through any two points.Three points that lie on the same line are described as being "collinear" points.
They satisfy the equation x + y = 0
Yes.
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.
