Question

For one of the solutions of the
equation ax + by + c = 0, x is
negative and y is positive then
surely a portion of line lies in the
quadrant.​

Answer 1

Answer:

it definitely lies in second quadrant

Step-by-step explanation:

Answer 2

Answer:

2nd Quadrant

Step-by-step explanation:

Concept= Cardinal system of lines

Given= Equation of line

To find= Quadrant of x and y

Explanation=

We have been provided with the information that in the equation ax + by + c = 0, x is negative and y is positive.

x= -

y= +

In the axis of number line we know that x axis is horizontal and y axis is vertical

At the center of these intersection lies the point (0,0).

This and other points are denoted by (x,y)  where x can be positive or negative and y can be positive or negative.

The positive x lies in the right of (0,0) and negative in the left.

Similarly in y positive lies above (0,0) and negative below it.

Now these values in total makes four quadrants as follows

(x,y)= +,+ = 1st quadrant

(x,y)= -,+ = 2nd Quadrant

(x,y)= -,- = 3rd quadrant

(x,y)= +,- = 4th quadrant

Here we know that given (x,y) is (-,+) which means it lies in the 2nd Quadrant.
