Answer: 0
Step-by-step explanation:
Slope (m) is defined by the formula change in y divided by the change in x. You could denote "change in" using Δ (delta).
The change in y is your final postion along the y-axis, subtracted by your initial position on the y axis.
The change in x is your final position among the x-axis, subtracted by your initial position.
Think of these two sets of coords like two positions. Your final y was 2, and your initial was also 2. Do 2 - 2 to get 0. We dont even need to solve for delta x because 0 divided by anything is zero. Therefore your slope will be 0. That basically means you have a critical point of the function. The tangent line will be completely horizontal along that interval of coords.
