The point(other than the origin) for which the abscissa is equal to the ordinate lie in---
i) quadrant I and III
ii) quadrant II and IV
iii) quadrant I only
1v) quadrant III only
Answers
answer : option (i) quadrant I and III
explanation : abscissa means value of x and ordinate means value of y,
any point in Cartesian coordinates is written by (x, y) or (abscissa, ordinate).
we know,
in first quadrant ⇔abscissa and ordinate both are positive.
in 2nd quadrant ⇔abscissa is negative and ordinate is positive.
in 3rd quadrant ⇔abscissa and ordinate both are negative.
in 4th quadrant ⇔abscissa is positive and ordinate is negative.
now a/c to question, abscissa is equal to ordinate. means The point will be like as (a, a) or (-a, -a) .
from above explanation this type of point only possible in 1st and 3rd quadrant.
so, answer is quadrant I and III.
Answer:
I and III quadrants as in I quadrant both are positive while in III quadrant both are negative please mark my answer brainliest
