The regular equation for something like this is y=mx+b in which the "m" is the slope. In this case, the slope would be 0.2/1.4 or 0.1/0.7 if reduced. This is because to get y by itself, you must divide all the coefficients on both sides by 1.4. So in y=mx+b form, the equation would look like: y=(.2/1.4)x+(2.3/1.4) The slope is approximately 0.143
