Answer:

#(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)#

In this equation, #y_1# is equal to the y-coordinate of your given point, #x_1# is equal to the x-coordinate of your given point, and #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) = -8x#
