What is the distance of the pointP(4,3) from the y-axis? |
|
Answer» Distance of point P(4,3) from Y - AXIS will be 4 units. The pt. is on y - axis so, its x co - ordinate will be 0. Also, we have to find distance between them. So, the distance between them will be perpendicular. Therefore, co-ordinates of point A on y - axis A(0, 3) d(AP)^2 = (X2 - X1)^2 + (Y2 - Y1)^2 = (4 - 0)^2 + (3 - 3)^2 = (4)^2 + 0 = 16 + 0 = 16 d(AP)^2 = 16 Therefore, d(AP) = 4 units {Taking SQUARE root on both SIDE} |
