Answer:
[tex]m =\dfrac{-3}{2}[/tex]
Step-by-step explanation:
To find the slope:
Choose any two points from the given graph.
Find the slope using the formula,
[tex]\boxed{\bf Slope = \dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(0, 0) ⇒ x₁ = 0 & y₁ = 0
(-12 , 18) ⇒ x₂ = -12 & y₂ = 18
[tex]\sf m = \dfrac{18-0}{-12-0}\\\\\\m =\dfrac{-18}{12}\\\\\\m = \dfrac{-3}{2}[/tex]
