FUNDEMENTAL Of Coordinate Geometry

Coordinate geometry is frightened by many students and today I am going to discuss the fundamental of coordinate geometry.

There are two axis X axis-horizontal and Y axis-perpendicular. There are 4 quadrants in the graph.

1st quadrant is positive for both x and y value      2nd quadrant is negative for x value and positive for y value      3rd quadrant is negative for both x and y value      4th quadrant is positive for x value and negative for y value

The equation of any straight line is y=mx+c

Where m=slope of the line

           C=constant

To determine the slope of any line, check the coefficient of x

For example, 2x+y=4

                             y=-2x+4

So slope is here=-2
