# How do you find the point-slope form of the equation of the line passing through the point (10,-9);m=-2?

$y = m x + n$
$y = m x + n \implies - 9 = 10 m + n$;
a is the slope of the equation, we found that as $- 2$;
$- 9 = \left(10 \cdot - 2\right) + n \implies - 9 = - 20 + n \implies n = 11$;
$y = m x + n \implies \underline{y = - 2 x + 11}$
