Question

Miss Heather asks her students to plot the following:
$A=(4,8),B=(8,4)$

Sarah submits the following graph as her answer.


Choose the correct option.

• A. Neither $A$ nor $B$ ia plotted correctly.
• B. Both $A$ and $B$ are plotted correctly.
• C. Only $B$ is plotted correctly.
• D. Only $A$ is plotted correctly.

Answer 1

The correct option is A Neither $A$ nor $B$ ia plotted correctly.

$\underset{–}{\text{To plot}A=(4,8):}$
Value on X-axis = 4
Value on Y-axis = 8

$\underset{–}{\text{To plot}B=(8,4):}$
Value on X-axis = 8
Value on Y-axis = 4

Plotting these points on the graph, we get:


Thus, both $A$ and $B$ are plotted incorrectly. In fact, Sarah has interchanged the points.

Thus, neither $A$ nor $B$ is plotted correctly.
