A line passes through the points in this table.
x y
9 7
19 12
29 17
39 22
What is the slope of the line?
To find the slope of the line passing through the points (9, 7) and (39, 22), we use the formula for slope:
Slope = (y2 - y1) / (x2 - x1)
Substitute the values from the points into the formula:
Slope = (22 - 7) / (39 - 9)
Slope = 15 / 30
Slope = 0.5
Therefore, the slope of the line passing through the points is 0.5.
