It provides information on the rate of change of one variable with respect to the other variable(s).
If you dont have slope then you cant tell
because right away you can tell the slope and y-intercept
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
The rate of change
That it descends.
you tell me
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.
it is impossible to tell the slope of a line graph without proper points to evaluate from.
G
looking at it
It is a horizontal line.
