Question

Write an equation of the line passing through the point A (3,-4) that is parallel to the line y= -x + 8.

Answer 1

Hi! Your answer is: y = -x -1

Explanation:

The x- and y-coordinates will be the same for the parallel line. This means we need to find the constant that needs to replace the +8 in the equation:
y = mx + b

1. y = -x +b (find with the coefficient of x)

2. -4 = -(3) +b

3. b = -1 and add 3 to both sides

Hope this helps! Have a good night! :)
