Answer 1

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
