Plugging in some values for p and q, lets say 120 and 8, respectively, we can get a finite answer of 1.5. However, as we expand P to infinity the resulting decimal equivalent will also go on infinitely. T...

statement 1 gives you the slope of line l is 3 times its y-intercept. Knowing this fact on it's own is insufficient to finding the slope of the line, as we have no reference point. Furthermore, if line l crosses above or below the x-axis that will affect the slope making it positive or negative, dep...
