Answer:
Slope = -3/4
Explanation:
Given two points on a line, we can find the line's slope (m) using the slope formula, which is given by:
m = (y2 - y1) / (x2 - x1), where
- m is the slope,
- (x1, y1) is one point on the line,
- and (x2, y2) is another point.
Thus, we can find the slope (m) by substituting (2, 9) for (x1, y1) and (18, -3) for (x2, y2) in the slope formula:
m = (-3 - 9) / (18 - 2)
m = -12 / 16
m = -3/4
Thus, the slope of the line that passes through the points (2, 9) and (18, -3) is -3/4.
