Question

plot the following points on the coordinate plane. $(-1\frac{3}{5},\frac{2}{5}), (1.4, -0.8), (-1,1)$

Explanation:

Step1: Convert mixed - number to decimal

$-1\frac{3}{5}=-\frac{8}{5}=-1.6$ and $\frac{2}{5} = 0.4$. So the first point is $(-1.6,0.4)$.

Step2: Locate the first point

On the coordinate plane, move 1.6 units to the left of the origin (since $x=-1.6$) and 0.4 units up (since $y = 0.4$) and mark the point.

Step3: Locate the second point

For the point $(1.4,-0.8)$, move 1.4 units to the right of the origin (because $x = 1.4$) and 0.8 units down (because $y=-0.8$) and mark the point.

Step4: Locate the third point

For the point $(-1,1)$, move 1 unit to the left of the origin (as $x=-1$) and 1 unit up (as $y = 1$) and mark the point.

Answer:

Points $(-1.6,0.4),(1.4,-0.8),(-1,1)$ are plotted on the coordinate - plane.
