What is the slope of the line that passes through the points left bracket, 0, comma, minus, 4, right bracket(0,−4) and left bracket, 30, comma, minus, 9, right bracket(30,−9)? Write your answer in simplest form.

The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:

slope = (y₂ - y₁) / (x₂ - x₁)

Substituting the given points, we find:

slope = (-9 - (-4)) / (30 - 0)
slope = (-9 + 4) / 30
slope = -5 / 30

Simplifying the fraction, we have:

slope = -1 / 6

Therefore, the slope of the line passing through the two points is -1/6.
