Answer: slope = - ⁹/₄
Step-by-step explanation:
The question gives us two points, (5, 18) and (9, 9), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (18 - 9) ÷ (5 - 9)
= - ⁹/₄
Checking my answer:
Finding the Equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 9 = - ⁹/₄ (x - 9)
To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.
