Question: In coordinate geometry, what is the slope of the line passing through the points (2, 3) and (4, 7)?
Options:
Correct Answer: 2
Solution:
The slope of a line is calculated using the formula (y2 - y1) / (x2 - x1). For the points (2, 3) and (4, 7), the slope is (7 - 3) / (4 - 2) = 4 / 2 = 2.
