Ответ:
The correct option is a.
Step-by-step explanation:
The given functions are
Both are linear functions and the parent function of linear functions is
If a line has large slope then it is more steeper.
The slope intercept form of a function is
where, m is slope and b is y-intercept.
Using slope intercept form we can say that the slope of first line is 1 and the slope of second line is 2.
Since the slope of second line is larger and twice of the slope of first line, therefore the graph is twice steeper as y=x.
Hence the correct option is a.
