Question
Let l be a line in the x-yplane. If l is a vertical line, its equation is x = a for some real number a.
Suppose l is not a vertical line and its slope is m. Then the equation of l is y = mx + b, where b is the y-intercept.
If l passes through the point (x₀, y₀), the equation of l can be written as y - y₀ = m(x - x₀).
If (x₁, y₁) and (x₂, y₂) are two points in the x-y plane and x₁ ≠ x₂, the slope of line passing through these points is m = (y₂ - y₁)/(x₂ - x₁).
