To find slope from a graph, we can choose any two points (x₁, y₁) or (x₂, y₂) on the graph and use the formula (y₂ - y₁) / (x₂ - x₁). Here x1 , y1 , x2 , y 2 are the coordinates of the graph. Whenever, the graph of a line is given, and we are asked to find the equation, the first step to find the equation is determining the slope of the graph.
