# Snake lemma and regular epi mono factorization
Suppose you have two exact sequences $0 \to A \to B \to C \to 0$ and $0 \to E \to F \to G \to 0$ and a morphism $\{a_i\}$ between them.
Then the snake lemma gives us an exact sequence $$0 \to \text{ker}(a_1) \to \text{ker}(a_2) \to \text{ker}(a_3) \to \text{coker}(a_1)... | HuggingFaceTB/finemath | |

Find the value of ‘a’, if the line through (–2, 3) and (8, 5) is perpendicular to y = ax +2
Solution :
Equation of the line passing through the points (-2, 3) and (8, 5).
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
