How do you know the relationship between x and y is proportional?

The answer depends on how the information is presented. If in the form of a graph, it must be a straight line through the origin. If in the form of an equation, it must be of the form y = cx.


Does the graph of an inverse variation pass through the origin?

Inverse variation does not pass through the origin, however direct variation always passes through the origin.


If the graph of a linear equation Ax plus By equals C passes through the origin then will C equal 0?

Yes Ax + By = C As the line passes through the origin then x = 0 when y = 0. Substituting gives, 0 + 0 = C therefore C = 0.


Do all linear equations need to be proportional?

No.A directly proportional graph has an equation of the form y = mx. It always passes through the origin.A linear graph will have an equation in the from y = mx + c. This has a y-intercept at (0, c). It doesn't pass through the origin unless c = 0. The directly proportional graph is a special case of a linear graph.


Why does the graph of an equation expressing direct variation always pass through the origin?

For a direct variation, y=kx where k is the constant of variation if x =0 then y=0 and the graph of y=kx passes through the origin. -Indiana Prentice Hall Algebra 2 Text Book.


State the y-intercept for the graph y equals -4x?

y = -4x The y-intercept is zero. That is, the graph passes through the origin.

How do you determine if a relation represents a function?

If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!


How does one find out if an equation's graph goes through the origin?

-- Take the equation -- Set either 'x' or 'y' equal to zero -- Solve the resulting equation for the remaining variable -- If the remaining variable is then also zero, then the origin is on the graph of the function If the graph is a straight line ('x' and 'y' appear in the equation only to the 1st power), then the equation has to be in the form of a simple ratio ... like (y = Kx) or (x = Ky) or (xy = K) or (x/y = K) ... in order to go through the origin.


How do you Graph the line that has a slope of 5 and passes through the origin?

-- Put a dot at the point where (x=1, y=5). -- Move your ruler so that the dot and the origin are both on the edge of the ruler. -- Draw a line along as much of the ruler as you want to. That line is the graph of y = 5x, which is the equation of the line you're describing.
