For Example: Find the Slope of this Line[br]       [br]         [img width=242,height=208]https://lh6.googleusercontent.com/_RFuqo42Nonh_li7bGfRzOwCl68Bav8C_1S_lqUU3p2tKjeX9soKwG5WkEYkhAkqM3cybhXiJRtK01Ft9KCQVdL22OPyMoNe3onpBMV99nJtHLKfClHgmKs4fPuyehoOqxup4-6r[/img][br]     (-4, 1) and (0, 2) are the points we are going to be using. (-4, 1) is (x1, y1) and (0, 2) is (x2, y2). Now taking the slope formula plug the numbers in it, (2 - 1) / (0 - (-4)), first do subtraction to both sets of parentheses and then divide. The answer resulting from calculating is 1 / 4. Now using the (rise / run), the rise is 1 and run is 4 so the slope is 1 / 4, receiving the same slope from both formulas.[br][br][br]
