What is the slope of a line with one point at (5,1) and another point at (7,2)?
A1/2incorrect answer
B1incorrect answer
C2incorrect answer
D1/3incorrect answer
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:
slope = (y₂ - y₁) / (x₂ - x₁)
Using the given points (5, 1) and (7, 2), we can substitute the values into the formula:
slope = (2 - 1) / (7 - 5)
= 1 / 2
Therefore, the slope of the line is 1/2. So, the correct answer is A.
