Question

use the equation to complete the table.
y = \frac{1}{2}x
now, graph the equation.

Explanation:

Step1: Substitute x=20 into equation

$y = \frac{1}{2} \times 20 = 10$

Step2: Substitute x=30 into equation

$y = \frac{1}{2} \times 30 = 15$

Step3: Substitute x=40 into equation

$y = \frac{1}{2} \times 40 = 20$

Step4: Substitute x=50 into equation

$y = \frac{1}{2} \times 50 = 25$

Step5: Plot points for graph

Points: $(20,10), (30,15), (40,20), (50,25)$; draw a straight line through them.

Answer:

Completed table:

x	y
30	15
40	20
50	25

Graph: Plot the points (20,10), (30,15), (40,20), (50,25) on the coordinate plane and connect them with a straight line extending through the origin (since $y=\frac{1}{2}x$ is a proportional linear equation).
