Given some coordinates, recognise which quadrant a point lies in, or which axis a point lies upon.

You can think of a pair of coordinates as a direction to the desired point, starting from the origin.

\n

The first part of the coordinates tells you how far to move along the horizontal \$\\,x\$-axis. Positive numbers are on the right and negative numbers are on the left.

\n

The second part of the coordinates tells you how far to move along the vertical \$\\,y\$-axis. Positive numbers are above the origin and negative numbers are below.

\n

#### a)

\n

The point lies in the:

\n

\$A\$ quadrant when the first part is positive and the second part is also positive.

\n

\$B\$ quadrant when the first part is negative and the second part is positive.

\n

\$C\$ quadrant when the first part is negative and the second part is also negative.

\n

\$D\$ quadrant when the first part is positive and the second part is negative.

\n\n

#### b)

\n

The point lies on the:

\n

\$X\$ axis when the \$y\$ coordinate of the point is zero.

\n

\$Y\$ axis when the \$x\$ coordinate of the point is zero.

\n

Origin when both the \$x\$ and \$y\$ coordinates are zero
