Question

If the perpendicular distance of a point P from the x-axis is 7 units and the foot of the perpendicular lieson the negative direction of x-axis, then the point P has:a) y-coordinate = 7 or –7 only b) y-coordinate = 7 onlyc) y-coordinate = –7 only d) x-coordinate = –7

Answer 1

Answer:

option b is correct or maybe option a .

point P has , - 7 as y - coordinate .

• measurement of x is not given .

• y is positive .

therefore , y has positive sign as + 7 only or negative also .
