The abscissa of a point is positive in:

Plot the following points and check whether they are collinear or not:
$(1,3), (-1,-1), (-2,-3)$

If $(x+2, 7)$ and $(2x-1, 7)$ are the same point,then $x = $ ...........

Which axis passes through the point $\left(7 \frac{3}{4}, 0\right)?$

In which quadrant or on which axis does each of the following points lie?
$A(15, -10), B(-10, -20), C(25, 0), D(-15, 25), E(-5, 0), F(0, -15), G(25, 5), H(0, 15)$
Verify your answer by plotting the points in the Cartesian plane. Use the scale $1 \, cm = 5 \, \text{units}$ on both axes.

Plot the points $P(1, 0)$,$Q(4, 0)$,and $S(1, 3)$. Find the coordinates of the point $R$ such that $PQRS$ is a square.
