A straight line can be represented in the form of a liner equation containing two variables x and y. When the equation is graphed on a pair of coordinate axes, the line passes cut through the axes in two points. The point where the line cuts the x-axes is called as its x coordinate and the point where the line cuts the y-axes is called as its y coordinate. In this way a line has x-intercept and y-intercept. The x-intercept of a line lies on x axes and is in the form (a,0). Similarly the y-intercept is in the form (0,b). To find the x-intercept of a line, substitute y = 0 in the equation of the line and solve for x. Similarly to find the y-intercept, substitute x = 0 in the equation of the line and solve for y. This video teaches x-intercept and y-intercept.
