Answer:
Option C is correct.
Explanation:
Given that if the graph y=x+5 changed to y=x+9 then we have to compare the two graphs.
As first graph given is y=x+5
which is the equation of straight line with slope 1 and intercept 5.
Second equation is y=x+9
which is also the equation of straight line with slope 1 but intercept 9.
The intercept of second graph is greater than the first
⇒ the graph of new function shifted up.
Option C is correct.
