WebSo you should read dy/dx = 1.5 as dy/dx = 1.5/1, which means that for one step on the x axis, we go one step and a half on the y axis. We can also say dy/dx = 1.5/1 = 3/2, for every two steps on the x axis, we take three steps on the y axis, this is equivalent. Lastly we also have dy/dx = 1.5/1 = 0.75/0.5.
