Question

Graph the function $\mathrm{y}=-3\mathrm{x}$

Answer 1

Step 1: Finding value of input and output (coordinates) or $\mathrm{x}$ and $\mathrm{y}$.

Input $\left(\mathrm{x}\right)$	Output $(\mathrm{y}=-3\mathrm{x})$	Ordered pair
$-1$	$\mathrm{y}=-3(-1)=3$	$(-1,3)$
$0$	$\mathrm{y}=-3\left(0\right)=0$	$(0,0)$
$1$	$\mathrm{y}=-3\left(1\right)=-3$	$(1,-3)$
$2$	$\mathrm{y}=-3\left(2\right)=-6$	$(2,-6)$

Step 2: Plotting the graph of function $\mathrm{y}=-3\mathrm{x}$

Mark all the ordered pairs on the graph to get the points.

And then draw a straight line passing through those points,

Hence, the graph of the function $\mathrm{y}=-3\mathrm{x}$ is shown above.
