WHAT IS THE METHOD TO FIND IF THREE POINTS ARE COLLINEAR? Collinear points are three or more points in one same plane which lie on a same straight line. To determine if three or more points are collinear, two formulas as exist in coordinate geometry can be used. they are: slope of a straight line and area of a triangle. the determinant formula can also be applied.

WHAT IS MEANT BY Y INTERCEPT OF A STRAIGHT LINE? Y intercept of a straight line L is y coordinate in the point on the y axis through which the straight line L is passing. Since y intercept is a coordinate, so it can be either positive or negative. To find the y intercept of a straight line L whose equation is given, set 0 in x to get rid of x which will then pave way for finding the y intercept. Similarly, x intercept is X coordinate in the point on x axis through which a line L is…

High School Math Adventures with Mrs. B: Distance and Midpoint Formula geometry

Let the coordinates of one point, A be (x1, y1) and of another point, B be (x2, y2). Let point C be the mid-point of the line segment AB, i.e. C is the point on the line segment AB that is exactly half-way from both the points A and B. In other words, it is equidistant from the two points A and B. Then, the formula to find the coordinates of this midpoint C of the line segment AB, called the "midpoint formula" is [(x1 + x2)/2, (y1 + y2)/2] .

Hands on activity - Turn your classroom into a Coordinate Plane to teach slope, graphing, distance formula, etc. A perfect hands-on activity. I would use this as a way to do hands on graphing practice with the whole class.
