Question

For what the value of a , the point (-2,-4) lies on the locus of ax-3y=14?​

Answer 1

Explanation:

The term locus means the set of all points in plane. So we are looking for the set of all points that lie on the graph

`ax - 3y = 14`

We know that

`a( - 2) - 3( - 4) = 14`

`- 2a + 12 = 14`

`- 2a = 2`

`a = - 1`
