Question

The distance from the origin to the point of intersection of the two straight lines 3x-2y=6 and 3x+2y=18 is
a)2 units
b)3 units
c)4 units
d)5 units

Answer 1

Answer:

Step-by-step explanation:

3x - 2y = 6 and 3x + 2y = 18 intersect at the point A(4 , 3). the distance from the origin O(0 , 0) to A(4 , 3) is given by sqrt(4^2 + 3^2) = sqrt(25) = 5. thus

OA = 5 units.
