Find the slope of a line that passes through (-10,-1) and (5,-4) a. -1/5 b. 1/3 c. 1 d. -3
The formula for finding the slope of a line passing through two points (x1, y1) and (x2, y2) is given by:
m = (y2 - y1) / (x2 - x1).
Using the coordinates of the given points (-10, -1) and (5, -4):
m = (-4 - (-1)) / (5 - (-10)) = -3 / 15 = -1/5.
Therefore, the slope of the line passing through (-10, -1) and (5, -4) is -1/5.
The correct answer is a. -1/5.
