How do we know when an equation represents a proportional relationship?
If it passes through the origin
How would you know if the equation is liner by just looking at the equation?
No powers also, no x times y i.e. xy = 1 is not linear
How do you know if a fraction is proportional?
All fractions are proportional to some other fraction.
How do you know is an equation is linear?
You know if an equation is linear if it is a straight line. You can also know if the equation is y = mx + b where there are no absolute values nor exponents.
How do you know if an equation is equivalent?
An equation is equivalent to another equation, if they have the same solution.

How do you know if a equation is a quadratic one?
You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.
How do you know if something is proportional?
if somthing is proportional is will either be Multiplying or Diving
If you are looking a graph of an quadratic equation how do you know where the solutions are?
They will be on the horizontal x axis of the graph (look for the x-intercepts).
How do you know if a fraction is proportional?
All fractions are proportional to some other fraction.
How do you know someone is looking at you?
You just know. Always truist your instinct.

What is the equation for finding the radius of a sphere?
That depends what you know about the sphere. For example, if you know the diameter, just divide it by 2 to get the radius.
How reactance is equal to 2pifL?
The equation of an inductor is ...di/dt = L / V... which means that the rate of change of current is proportional to voltage and inversely proportional to inductance.Set this up in a sinusoidal forcing circuit and solve the differential equation, or use phasors, and you get ...XL = 2 pi f L... which means that inductive reactance is proportional to both frequency and inductance by the factor of 2 pi.I have not included the derivation, because I don't know how to do it, and it does not seem necessary. If someone wants to provide one, please feel free to refine the answer.
How do you find the y intercept on a parabola?
If you know the equation, you just plug in x = 0 and solve.
How do you know if a guy you dont know likes you at church?
If a guy you don't know likes you at church, he will typically try to look at you when you are not looking and may look away if you catch him looking. Why don't you just ask him why he is looking at you.
