In Exercises 91102, use an inverse matrix to solve (if possible) the system of linear equations. 12x3x13y2y20

L6 - 5 A secant line is a line joining two points on a curve. On our example, consider the slope of the secant line through 1) [1,3] 2) [1,2] We observe: Slope of secant line Notice that the secant lines in our above graph approach a unique line, called the tangent line of the graph at t =1 . Slope of the tangent line
