Question

4a
lets try that again
the graph of $y=3x$ is shown below.
a constant is added to the equation to get $y=3x-3$.
complete the table of values for the new equation $y=3x-3$.

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

Explanation:

Step1: Substitute x=-1 into $y=3x-3$

$y=3(-1)-3=-3-3=-6$

Step2: Substitute x=0 into $y=3x-3$

$y=3(0)-3=0-3=-3$

Step3: Substitute x=1 into $y=3x-3$

$y=3(1)-3=3-3=0$

Step4: Substitute x=2 into $y=3x-3$

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

Answer:

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