Answer:
The gradient of the parallel line is -2.
Explanation:
Parallel lines have the same gradient.
We find the gradient of the given line by solving the equation for y.
2x + y = 4
Subtract 2x from both sides.
y = -2x + 4
The equation is now written in the y = mx + b, where m is the gradient.
The gradient of the given line is -2.
The gradient of the parallel line is -2.
