Question

Find the equation of the line shown

Answer 1

The equation of the line is:

`y = x + 1`

Explanation:

The equation of a line has the following format:

`y = mx + b`

In which m is the slope(suppose we have two points, the slope is the change in y divided by the change in x).

b is the y-intercept(the value of x when y = 0).

In this question:

When
`x = 0, y = 1`, so
`b = 1`

Passes through the points (0,1) and (1,2). So the slope is

`m = (2-1)/(1-0) = 1`

The equation of the line is:

`y = x + 1`
