slope of new line = -1/(-2/3) = 3/2
---
y + 9 = (3/2)(x - 7)
y = (3/2)x - 7(3/2) - 9
y = (3/2)x - 21/2 - 18/2
y = (3/2)x - 39/2

The given equation has slope = (-2/3)
Your equation must have slope = 3/2
---------
Form of the desired equation:
y = mx + b
Substitute and solve for "b":
-9 = (3/2)7 + b
-18/2 = 21/2 + b
b = -39/2
--------
Equation::
y = (3/2)x - (39/2)
