How to represent y = -2x + 17 using a table?

Answer 1

Basically, what you need to do is to create a table with columns x and y.

First, you take any value of x (let's say 0), and substitute it into equation y = -2x+17.

If we substitute this x = 0, we get y = -2*0+17, or y = 17.

From this we get when x = 0, y = 17. That's our first row in a table.

Next, we substitute another value for x. Let's choose x = 1. From this we get

y = -2*1+17

= -2+17

= 15

What this means is that when x = 1, then y = 15. You get the pattern from here.

Now we can substitute other values of x, such as

x = 2,

x = 3, etc. Calculating the equation again we get

when x = 2, y = -2*2+17 = 13

and x = 3, y = -2*3+17 = -6+17 = 11

Now we can create the table

x y

0 17

1 15

2 13

3 11

And that's how we represent an equation using a table.

Answer 3

Select a value for x, substitute into equation, calcualte the value of y.

Select another value for x, substittue into equation, calculate thevalue of y.

Repeat as often as required.

Such a table should be in your text book.
