Question

Given the equation, y=3x, complete the table of values

x (input)
y (output)

-2
-1
0
1
2

Answer 1

To find the answers you just need to multiply each value by 3. This is as we are given the information that y is equal to 3x. If we know this and we know the values of x we can easily work out the output (y)!!

• -2 = 3 x -2 = -6
• -1 = 3 x -1 = -3
• 0 = 3 x 0 = 0
• 1 = 3 x 1 = 3
• 2 = 3 x 2 = 6

We can also see a pattern of +3 going upwards!!

Hope this helps, have a great day!
