Question 855018: I keep confusing myself on how to substitute given points. Write the equation of a line parallel to the given line but passing through the given point. y= -x+3 (-2,-2)I know I substitute -1 in for x, but I come up with y=-x-2 as my answer. I have an assignment due today and I'm making bad mistakes.

Write the equation of a line parallel to the given line but passing through the given point. y= -x+3 (-2,-2)
------
slope = -1
-------
Form: y = mx + b
Solve for "b":
-2 = -1*-2 + b
b = -4
--------
Equation:
y = -x - 4
------------------
