Two points that lie on the line are (6, 0) and (0, -6).
The slope of the line passing through points $(x_1, y_1)$ and $(x_2, y_2)$ is given by:
$m = \frac{y_2 - y_1}{x_2 - x_1}$
Using the points (6, 0) and (0, -6):
$m = \frac{-6 - 0}{0 - 6} = \frac{-6}{-6} = 1$
The y-intercept is the point where the line crosses the y-axis. In this case, the line crosses the y-axis at (0, -6), so the y-intercept is -6.
The slope-intercept form of a linear equation is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept.
Using the calculated slope $m=1$ and y-intercept $b=-6$, the equation of the line is:
$y = 1x - 6$ or $y = x - 6$
