Answer:
Option D. 7
Explanation:
The given function in the graph is a linear function, represented by the
f(x) = mx + c
Here m is the slope and c is the y intercept.
For any linear function initial value of the function is f(0) for x = 0
f(0) = m×0 + c
= c
For the given graph in the figure attached y- intercept is 7. Therefore, option D. 7 is the correct option.
