Answer 1

`y = 3x - 2`

Explanation:

Required

The equation of the above linear function

From the table, we have:

`(x_1,y_1) = (1,1)`

`(x_2,y_2) = (2,4)`

Calculate slope (m)

`m = (y_2 -y_1)/(x_2 -x_1)`

`m = (4 -1)/(2 -1)`

`m = (3)/(1)`

`m =3`

The equation is:

`y = m(x - x_1) + y_1`

So, we have:

`y = 3(x - 1) + 1`

`y = 3x - 3 + 1`

`y = 3x - 2`
