$(y - 9) = - 8 x$ $(y - 9) = -8x$

Explanation:

The slope intercept form for a linear equation is self-explanatory; all you need is any point on the line and its slope. The general equation for this form is:

$(y - y_{1}) = m (x - x_{1})$ $(y - y_1) = m(x - x_1)$

In this equation, $y_{1}$ $y_1$ is equal to the y-coordinate of your given point, $x_{1}$ $x_1$ is equal to the x-coordinate of your given point, and $m$ $m$ is equal to the slope. Since we have all three of these values, all we need to do is plug them in:

$(y - 9) = - 8 (x - 0)$ $(y - 9) = -8(x - 0)$
$(y - 9) = - 8 x$ $(y - 9) = -8x$
