Ответ:
The slope is fraction negative 1 over 2 throughout the line.
Step-by-step explanation:
The slope (m) of a line is computed as follows
m = (y2 - y1)/(x2 -x1)
where (x1, y1) and (x2, y2) are the coordinates of 2 points of the line. Taking, for example, points (0, 0) and (-4, 2), the slope is:
m = (2 - 0)/(-4 -0) = -1/2
Then, the slope is -1/2 throughout the line.
