(A) To plot the points on a graph paper,follow these steps:
$1$. Draw two perpendicular lines,$X'OX$ (x-axis) and $Y'OY$ (y-axis),intersecting at the origin $O(0, 0)$.
$2$. Choose a scale: $0.5 \ cm = 1 \ unit$ on both axes.
$3$. Plot each point based on its coordinates $(x, y)$:
- For $A(1, 3)$,move $1 \ unit$ to the right of the y-axis and $3 \ units$ above the x-axis.
- For $B(-3, -1)$,move $3 \ units$ to the left of the y-axis and $1 \ unit$ below the x-axis.
- For $C(1, -4)$,move $1 \ unit$ to the right of the y-axis and $4 \ units$ below the x-axis.
- For $D(-2, 3)$,move $2 \ units$ to the left of the y-axis and $3 \ units$ above the x-axis.
- For $E(0, -8)$,stay on the y-axis and move $8 \ units$ below the x-axis.
- For $F(1, 0)$,move $1 \ unit$ to the right of the y-axis and stay on the x-axis.
