equation of a line

Hello angela!

Determine the equation of a line passing through the point (5,-3) with an undefined slope.

The undefined slope is m.  m is the tangent of the angle of inclination.

m = (y - y₁) / (x - x₁)

y - y₁ = m * (x - x₁)

y = m * (x - x₁) + y₁

The equation of a line passing through the point (5,-3)

with an undefined slope is

y = m * (x - 5) - 3
