Question

The line passes through the points (x1, y1) and (x2, y2). The slope of the line is: a) x2−x1y2−y1​ b) y2−y1x2−x1​ c) x1−x2y1−y2​ d) y1−y2x1−x2​

Answer 1

b

Explanation:

the slope m of a line passing through (x₁, y₁ ) and (x₂, y₂ ) is

m =
`\frac{y_{2-y_(1) } }{x_(2)-x_(1) }` ← slope formula
