Question

directions: complete each table, then graph

1. $y = 2x$

$x$	$y$
$-3$
$-1$
$2$
$4$

(and a coordinate grid graph)

Explanation:

Step1: Substitute $x=-5$ into $y=2x$

$y=2\times(-5)=-10$

Step2: Substitute $x=-3$ into $y=2x$

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

Step3: Substitute $x=-1$ into $y=2x$

$y=2\times(-1)=-2$

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

$y=2\times2=4$

Step5: Substitute $x=4$ into $y=2x$

$y=2\times4=8$

Step6: List points for graphing

Points: $(-5,-10), (-3,-6), (-1,-2), (2,4), (4,8)$; plot and connect with a straight line.

Answer:

Completed table:

$x$	$y$
-3	-6
-1	-2
2	4
4	8

Graph: Plot the points $(-5,-10)$, $(-3,-6)$, $(-1,-2)$, $(2,4)$, $(4,8)$ on the coordinate grid, then draw a straight line passing through all these points (the line will pass through the origin and have a positive slope).
