.Write equation of x-axis |
|
Answer» We know a general equation of a straight line is,y=mx+cWhere c is the intercept of the line on y-axis and m is the gradient of the line. Since intercept of x-axis on y-axis is zero, so c=0. Gradient of x-axis is also zero because it makes an angle zero with itself. So m=tan(theta)=0. Putting these values in the general equation we get,y=0*x+0y=0. Thus we get the equation for x-axis as y=0. can we write (5,0) yes |
