<span>1. First, label the axis on your graph, with units:
time on the x-axis, in units of hours;
distance on the y-axis, in units of miles.
2. Draw a graph of distance vs. time. Distance after the first hour = 69 miles, distance after the 2nd hour = 138 miles, etc.
3. Observe that this graph is a STRAIGHT LINE with constant slope. Therefore the relationship is PROPORTIONAL.
For every other kind of graph -- i.e. not a straight line -- the relationship is NON-PROPORTIONAL.

The ratio of sediment yield of a drainage basin to the total amount of sediment moved by sheet erosion and channel <span>erosion.</span>
Since you didn't give the actual equation, I can only help with the mean of each part.
Q1: The coefficient of x is called the slope. That is the number in front of the x.
Q2: The constant term is the y-intercept. That is the number at the end of the equation.
