y − y₁ = m(x − x₁)
Used when slope and one point on the line are known.
m = (y₂ − y₁) / (x₂ − x₁)
Slope represents the rate of change between two points.
Point slope form is used to write the equation of a line when the slope and one point on the line are known.
Formula:
y − y₁ = m(x − x₁)
Point slope form is widely used in algebra, coordinate geometry, physics and engineering to describe linear relationships.
Point slope form is used to represent the equation of a line using slope and a known point.
It is used when slope and one point on the line are already known.
