Question 581341
The equation we seek has the same slope as the given equation because we know they are parallel. We use the point-slope formula, the given point (-4,2) and given slope -1. Do you see in your equation -x? There is an invisible -1 next to x. 

So, -x is the same as -1x. 

The coefficient of x ( the number next to x) is the slope of the line. 

y - (y coordinate of your point) = m(x -(x coordinate of your point) 

Let m = slope of the line 

y - 2 = -1(x -(-4)) 

y - 2 = -1(x + 4) 

y - 2 = -x - 4 

y = -x - 4 + 2 

ANSWER: y = -x - 2
