these are three ways to describe graphs in slope
Step-by-step explanation:
(1) Verbally slope indicates the steepness of a line (the sign indicates direction and the absolute value describes the steepness -- the larger the absolute value the steeper the graph.) This is related to the grade of a hill or the pitch of a roof.
(2) Algebraically slope is typically represented by m: for instance the equation of a line can be written as y=mx+b where m represents the slope. Also the slope formula where m=(y_2-y_1)/(x_2-x_1) . However, some linear functions use other letters for the value that is the slope of the graph such as a direct variation y=kx where k is the constant of proportionality.
(3) Graphically slope is often represented as rise over run, or (Delta y)/(Delta x) , or the ratio of the change in the vertical direction to the change of the horizontal.
