Well one way to think of this since the equation is going through the origin is to recognize this linear function as proportional and can be represented by y = kx.. Where 'k' represents the constant of proportionality. We can find the constant of proportionality by asking ourselves what can we multiply the x coordinate by to get the y coordinate for each point on the line? Consider the point (1, n) You can see the constant of proportionality would be 'n' and our equation would then be y = nx
