The rate of change of function 1 is 2
What is line?
A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely.
Given function: y = 2x + 7.
As the graph of function 1 is not given.
the rate of change of function 2 : y = 2x + 7.
As the the value of m or rate of change of above equation is 2
m=2.
as, the horizontal line passes, the rate of change is 0
Hence, rate of change is 2.
