During a field trip to an amusement park, a teacher asked her students to determine the slope at a specific point of the roller coaster ride. A portion of the path of the ride can be described using the following parametric equations:

     x = 100t²
     y = 100(t³ - 2t)

for -1.5 ≤ t ≤ 0.

Determine the tangent when t is -1.1.

• Note that the parametric equations are defined for an interval of t only (i.e., -1.5 ≤ t ≤ 0).
