Question

Draw the graphs of lines x = 2.5 and $y=\frac{-7}{2}$ on the same graph paper; write the co-ordinates of the point of intersection of the lines.

Answer 1

$x=2.5$

This equation is of the form x = a.
Hence, graph of this equation is a line parallel to Y-axis at a distance of 2.5 units in the positive direction of X-axis.

$$\begin{gathered} y=\frac{-7}{2} \\ \Rightarrow y=-3.5 \end{gathered}$$

This equation is of the form y = a.
Hence, graph of this equation is a line parallel to X-axis at a distance of 3.5 units in the negative direction of Y-axis.




The coordinates of the point of intersection are (2.5, $-$3.5) .
