Determine the slope.

Start by selecting two points on the line, such as (6, 0) and (0, −2).

Use them to find the rise and the run and then calculate the slope.

Divide the rise, −2, by the run, 6, to determine the slope.

Find the equation of the line.

Use the *y*-intercept for *b* and the slope for *m* in the equation *y* = *mx* + *b*.
