Question

Find the equation of the line shown

Answer 1

`y = 2x - 1`

Explanation:

The line shown is a straight line its equation is of the form.

`y = mx + c`

Where m is the slope and c is the y-intercept.

From the graph, the slope is

`m = (rise)/(run)`

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

The y-intercept from the graph is where the line intersects the y-axis, so c=-1

We substitute the values to get:

`y = 2x - 1`
