Question

Write the coordinates of the points marked in the graph.

Answer 1

We can see the given graph that point $A$ is at a distance of $3$ units from the $y-axis$ and at a distance zero units from the $x-axis$.

Therefore, the $x-coordinate$ of $A$ is $3$ and $y-coordinate$ is $0$.

Hence, the coordinates of $A$ are $(3,0)$.

Similarly,

• The coordinates of $B$ are $(2,0).$
• The coordinates of $C$ are $(-1,0).$
• The coordinates of $D$ are $(-2.5,0)$.
• The coordinates of $E$ are $(-4,0)$.

So, as observed in figure, every point on the $x-axis$ has $0$ distance from the $x-axis$.

Therefore, the coordinate of a point lying on $x-axis$ is always zero and the $x-axis$ is denoted by the equation $y=0$.
