Tamil Nadu Board Solutions for Chapter: Algebra, Exercise 34: Exercise 3.8

The $x$-coordinate is always _____ on the $y$-axis.

_____ coordinates are the same for a line parallel to $Y$-axis.

$(-10,20)$lies in the second quadrant.

$(-9,0)$ lies on the $x$-axis.

The coordinates of the origin are$(1,1)$.

Find the quadrants without plotting the points on a graph sheet.

$(3,-4),(5,7),(2,0),(-3,-5),(4,-3),(-7,2),(-8,0),(0,10),(-9,50)$

Plot the following points in a graph sheet.

$A(5,2), B(-7,-3), C(-2,4), D(-1,-1), E(0,-5), F(2,0), G(7,-4), H(-4,0)$, $I(2,3), J(8,-4), K(0,7)$.

Use the graph to determine the coordinates where each figure is located.
