The rate of change
That it descends.
slope is change in y over change in x
If the line slants up and to the right, it has a positive slope. If it is slanting up and to the left, it has a negative slope.
looking at it
If you dont have slope then you cant tell
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
because right away you can tell the slope and y-intercept
you tell me

it is impossible to tell the slope of a line graph without proper points to evaluate from.
It is a horizontal line.
looking at it
Its angle of incline.
