5. Find the slope of a line going through each set of points. Then describe the line. Determine the slope formula by circling your choice. (1 m=\frac{y_{2}+y_{1}}{x_{2}+x_{1}} m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} m=\frac{x_{2}+x_{1}}{y_{2}+y_{1}} m=\frac{x_{2}-x_{1}}{y_{2}-y_{1}} Use your answer from Part I to find the slope of a line going through each set of points.Then describe the line as positive, negative, zero, or undefined. Show your work andexplain your answer. \text { A. }(5,7) \text { and }(-4,-2) \text { (3 points) } B. (1, 3) and (1, -10) (3 points)
