Final answer:
The slope of the line passing through the points (-4, -10) and (-7, -19) is 3.
Step-by-step explanation:
To find the slope of a line passing through two points, we can use the formula m = (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the points.
In this case, the points are (-4, -10) and (-7, -19).
Using the formula, we have m = (-19 - (-10))/(-7 - (-4)) = -9/-3 = 3.
Therefore, the slope of the line passing through the points (-4, -10) and (-7, -19) is 3.
