y=3x-4 input/output table

Question

how do you do this problem because i am confused

Answer 1

The equation is y = 3x - 4. We need to set up an input and output table. We need to remember that x values are inputs and y values are outputs. We give the x values or independent values and plug/ substitute it in the equation. The y values or the answers we get after plugging in the x values are the outputs of the equation.

For example

x (input) equation 3x - 4 = y y (output)

-1 3(-1)-4 = -3-4 -7

0 3(0)-4= 0-4 -4

1 3(1)-4 = 3-4 -1

2 3(2) - 4- 6-4 2

We set them up in a table format which is easier to pug in the values and get the x and y values.
