# How do you write an equation in slope intercept form given that the line passes through the Point: (1, 9); Slope: 5?

$y = 5 x + 4$
Use the relationship between the coordinates of your poin and the slope $m$ as:
$y - {y}_{0} = m \left(x - {x}_{0}\right)$
$y - 9 = 5 \left(x - 1\right)$
$y = 5 x - 5 + 9$
$y = 5 x + 4$
