Finding the Equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 8 = -⁵/₂ (x - 0)
y - 8 = -⁵/₂ x
we could also transform this into the slope-intercept form ( y = mx + c)
since y - 8 = - ⁵/₂ x
⇒ y = - ⁵/₂ x + 8
To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.
