A line passes through the points in this table.
x y
7 21
15 15
23 9
31 3
What is the slope of the line?
The slope of a line can be calculated using the formula: slope = (y2 - y1) / (x2 - x1)
Using the points (7, 21) and (15, 15) from the table:
slope = (15 - 21) / (15 - 7)
slope = -6 / 8
slope = -0.75
Therefore, the slope of the line is -0.75.
