Answer:
y = -2x
Explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = -2x + 3. Its slope is -2. A line parallel to this one will also have a slope of -2.
Plug this value (-2) into your standard point-slope equation of y = mx + b.
y = -2x + b
This question only asks for a line parallel to y = -2x + 3.
This means we can plug in any number (except 3) for b. We cannot plug in 3 because then it will be the same equation!
To make things simple, we can use 0 and therefore leave it out.
y = -2x
This line is parallel to y = -2x + 3.
Hope this helps!
