Question

given the function below, fill in the table of values and use the table values to graph.
$y = -3x$

$x$	$y = -3x$
$-2$
$-1$
$0$
$1$
$2$
$3$

Explanation:

Step1: Substitute $x=-3$

$y = -3\times(-3) = 9$

Step2: Substitute $x=-2$

$y = -3\times(-2) = 6$

Step3: Substitute $x=-1$

$y = -3\times(-1) = 3$

Step4: Substitute $x=0$

$y = -3\times0 = 0$

Step5: Substitute $x=1$

$y = -3\times1 = -3$

Step6: Substitute $x=2$

$y = -3\times2 = -6$

Step7: Substitute $x=3$

$y = -3\times3 = -9$

Answer:

$x$	$y=-3x$
$-2$	$6$
$-1$	$3$
$0$	$0$
$1$	$-3$
$2$	$-6$
$3$	$-9$

To graph this function, plot the points $(-3,9), (-2,6), (-1,3), (0,0), (1,-3), (2,-6), (3,-9)$ on a coordinate plane and draw a straight line through them.
