Final answer:
The slope of the line that contains the points (-4,3) and (0,-3) is -1.5.
Step-by-step explanation:
The slope of a line can be found using the formula slope formula:
m = (y2 - y1) / (x2 - x1)
Given the points (-4,3) and (0,-3), we can substitute the values into the formula to find the slope:
m = (-3 - 3) / (0 - -4)
= -6 / 4
= -1.5
Therefore, the slope of the line that contains the points (-4,3) and (0,-3) is -1.5.
