Linear Graphs

The coordinates of the origin are $(0,0).$

A point whose$y$ coordinate is zero and $x$-coordinate is $5$ will lie on $y$-axis.

A point whose $x$ coordinate is zero and $y$-coordinate is non-zero will lie on the $y$-axis.

Plot the points $\mathrm{K}(2,3), \mathrm{L}(5,3), \mathrm{M}(5,5), \mathrm{N}(2,5)$ on a graph sheet. Verify if they lie on a line.

Plot the points $\mathrm{P}(1,1), \mathrm{Q}(2,2), \mathrm{R}(3,3), \mathrm{S}(4,4)$ on a graph sheet. Verify if they lie on a line.

Write the coordinates of the vertices of each of these adjoining figures.

Draw the line passing through $(2,3)$ and $(3,2).$ Find the coordinates of the points at which this line meets the $x$- axis and $y$-axis.

Plot the points $\mathrm{A}(4,0), \mathrm{B}(4,2), \mathrm{C}(4,6), \mathrm{D}(4,2.5)$ on a graph sheet. Verify if they lie on a line.
