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.
Transformations of the quadratic function - graphic organizer. Students love having all of the transformations on one clear sheet that they can refer to often. Two fill-in versions included for different levels!!!
Y intercept of a straight line L is the 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 of a straight line is the x coordinate in the point on the x axis through which the line L is passing.
