To find the slope(m), use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] And plug in the two points
(0, 18) = (x₁, y₁)
(3, 2) = (x₂, y₂) [lines go from left to right, so the point furthest to the left is the 1st point]
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m =\frac{2-18}{3-0}[/tex]
[tex]m=\frac{-16}{3}[/tex] You can't simplify, so this is your slope
