Nothing, no numbers will add to 18 and multiply to -8
1/4 is the slope!
That equation is in slope intercept form aka y=mx+b. M is the slope, and b is the y intercept
In that equation, m=1/4 therefore 1/4 is the slope
Hope this helps!
This is in the form of a slope formula where y=mx+b. B pretty much gives you the vertical shift. Meaning that y=2/x-3 would be correct.
