If $(2a + 5, 3b + 2)$ and $(a + 11, b + 14)$ are coordinates of the same point,then the values of $a$ and $b$ are $\ldots$ respectively.

Plot the points $(x, y)$ given by the following table:

$x$	$2$	$4$	$-3$	$-2$	$3$	$0$
$y$	$4$	$2$	$0$	$5$	$-3$	$0$

In which quadrant or on which axis does each of the following points lie?
$A(10, 40), B(-30, 0), C(50, -40), D(0, -30), E(-20, 50), F(0, 60), G(70, 0), H(-40, -50)$
Verify your answer by plotting the points in the Cartesian plane. Use the scale $1 \, cm = 10$ units on both axes.

Plot the following points and write the name of the figure obtained by joining them in order:
$P(-3, 2), Q(-7, -3), R(6, -3), S(2, 2)$

The points $(1, -1), (2, -2), (4, -5), (-3, -4)$:

Write the coordinates of each of the points $P, Q, R, S, T$ and $O$ from the given figure.
