Question

A line's graph is shown. Write an equation for the line.​

Answer 1

`y = 1`

Explanation:

Given

Attached graph

The graph equation

Pick any two points, we have:

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

`(x_2,y_2) = (3,1)`

Calculate slope (m)

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

`m = (1 - 1)/(3 - 1)`

`m = (0)/(2)`

`m = 0`

The equation is then calculated using:

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

This gives:

`y = 0* (x - x_1) + 1`

`y = 1`

Hence, the equation is:

`y = 1`
