Answer:
y= -2x-2
Explanation:
All parallel lines have the same slope. So, the line we create must have a slope of -2. If we multiply the x value by -2, we can find b through an equation.
-4 would be x in this case because it's a point we pass.
So, our equation would be
y= -2(-4)+b
y=8+b
Now, we know that y is 8+b. We can find b by plugging in y=6, because those are the coordinates of P.
6=8+b
b=-2
Now we know that b is -2. We put this into the equation for the parallel line and get:
y=-2x-2
