If the foot of the perpendicular from the origin to a straight line isat `(3,-4)`, then find the equation of the line. |
Answer» Correct Answer - 3x-4y=25 Let P(3,-4) be the foot of the perpendicular from the origin O on the required line. Then the slope of OP is `(-4-0)/(3-0) = -(4)/(3)` Therefore, the slope of the required line is 3/4. Hence, its equation is `y+4 = (3)/(4)(x-3)` or 3x-4y = 25 |
