The point slope equation of a line is:

$y - y_1 = m(x - x_1)$

where the slope is $m$, and the point is $(x_1, y_1)$

You were given slope = m = -2/3, and point (1, 7).

Use the equation above and 
(1) replace m with your given slope, $-\dfrac{2}{3} $, 
(2) replace $x_1$ with 1, and 
(3) replace $y_1$ with -7.

$ y - y_1 = m(x - x_1) $

$y - (-7) = -\dfrac{2}{3}(x - 1)$

What does y - (-7) simplify to?
