Final answer:
The slope of the line passing through the points (-4,5) and (-7,8) is -1.
Step-by-step explanation:
To find the slope of a line passing through two points, we can use the formula:
slope = (y2 - y1) / (x2 - x1)
Using the points given (-4,5) and (-7,8), we can substitute the values into the formula:
slope = (8 - 5) / (-7 - (-4)) = 3 / -3 = -1
So, the slope of the line that passes through the points (-4,5) and (-7,8) is -1.
