Find the slope of a line that passes through (-10, -1) and (5, -4)
A. -3
B. -1/5
C. 1/3
D. 1
The slope of a line passing through two points (x1, y1) and (x2, y2) can be calculated using the formula:
Slope = (y2 - y1) / (x2 - x1)
Given the points (-10, -1) and (5, -4), we can substitute the values into the formula:
Slope = (-4 - (-1)) / (5 - (-10))
Slope = (-4 + 1) / (5 + 10)
Slope = -3 / 15
Slope = -1/5
Therefore, the slope of the line passing through (-10, -1) and (5, -4) is B. -1/5.
