Find the slope of the line through (–9, –10) and (–2, –5).
A. –five-sevenths
B. seven-fifths
C. five-sevenths
D. –negative seven-fifths
The slope of a line passing through the points (x1,y1) and (x2,y2) is given by the formula:
slope = (y2 - y1) / (x2 - x1)
Using the coordinates given in the problem, we have:
slope = (-5 - (-10)) / (-2 - (-9))
slope = 5 / 7
Therefore, the answer is (C) five-sevenths.
