Answer 2

SOLUTION  

TO DETERMINE  

The Location of the following points on the cartesian plane  

(0,a)  

(a,0)  

(-a, 0)  

(0,-a)

EVALUATION  

Abscissa = x  

Ordinate = y  

Let us assume that a > 0  

CHECKING FOR THE POINT (0,a)  

For the point (0,a)  

Abscissa = 0  

Ordinate = a which is positive  

So the point lies on Positive Y axis  

CHECKING FOR THE POINT (a,0)  

For the point (a, 0)  

Abscissa = a which is positive

Ordinate = 0  

So the point lies on Positive X axis  

CHECKING FOR THE POINT (-a,0)  

For the point (-a, 0)  

Abscissa = - a which is negative  

Ordinate = 0  

So the point lies on the Negative X-axis  

CHECKING FOR THE POINT (0,-a)  

For the point (0,-a)  

Abscissa = 0  

Ordinate = - a which is negative  

So the point lies on the Negative Y-axis
