If point P lies on the line y = -1, then its x and y coordinates are
x = -1, y = -1
x = -2, y = -1
y = 1, x = -1
y = -1, x can be any real number.
Since it is given that the point P lies on the line y = -1, it's y-coordinate will be -1.
Its x-coordinate, however, can be any real number.
If point P lies on the line y=−1, find the following a) Its Y-coordinate b) Its X-coordinate
If the straight lines x−12=y+1K=z2 and x+15=y+12=zK are coplanar, then the plane(s) containing these two lines is/are
