On the grid below, which point is located in the quadrant where the x- and y-coordinates are both negative numbers?
1 answer:
Answer:
Point C
Step-by-step explanation:
Given
See attachment for grid
Required
Which point is x and y = negative
From the attached grid, we have the following points
From the above points, only point C has negative x and y
<em>Another way to go about it is:</em>
Quadrant 3 has negative x and y values and point C is located in quadrant C.

As points, x-intercepts take the form 
, so to find the intercepts we can set 
and solve for 
.
From the first equation alone, we already know that
is a solution, which means one intercept is 
.
The second equation gives
so that the second intercept occurs at
.
So if
and 
, we have 
, giving C as the answer.
