Answer:
Explanation:
To find the slope of the line that contains the points (1, -9) and (-3, 3), we can use the formula for the slope of a line:m = (y2 - y1) / (x2 - x1)Plugging in the given points:m = (3 - (-9)) / (-3 - 1)m = 12 / -4m = -3So the slope of the line that contains the points (1, -9) and (-3, 3) is -3.
