The graph shows the relationship between x, the amount of time in hours and y, the distance traveled in miles, by a probe before it reaches mars.

Yes, the graph represents a proportional relationship, because it is a straight line that passes through the origin.

Step-by-step explanation:

The equation of a line that passes through the origin (which is located at the point ) has the following form:

Where "m" is the slope of the line.

By definition, Proportional relationships have the following form:

Where "k" is the Constant of Proportionality.  

Based on this, you can conclude that the graph of a Proportional relationship is a straight line that passes through the origin.

You can  notice in the figure that the that the graph that shows the relationship between the amount of time in hours and the distance traveled in miles by a probe before it reaches Mars, is a straight line that passes through the origin.

Therefore,  you can conclude that the graph represents a proportional relationship.

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.
