$y = 2 - 4 x$ $y=2-4x$

Explanation:

We need to find the slope of the line. To do this we use the following
$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $m=\frac{y_2-y_1}{x_2-x_1}$

Plugging in the points we are given we get
$m = \frac{- 6 + 2}{2 - 1} = - \frac{4}{1} = - 4$ $m=\frac{-6+2}{2-1}=-4/1=-4$

We can use point-slope form to find the equation
$y - y_{0} = m (x - x_{0})$ $y-y_0=m(x-x_0)$
$y + 2 = - 4 (x - 1)$ $y+2=-4(x-1)$
$y + 2 = - 4 x + 4$ $y+2=-4x+4$
$y = 2 - 4 x$ $y=2-4x$
