Ah- I'm not entirely sure what you mean but. To find the slope (which I think that's what you mean) you do... difference in y/ difference in x 3 - (-1) / 7 - 1 = 3 + 1 / 6 = 4/6 = 2/3 So k, or the slope would be 2/3 (Or if you're asking for an equation... use 3 - (-1) / 7 - 1) (I'm so sorry for not being super helpful to you!)
