10. The number of people, N, employed in a chain of cafes is related to the number of cafes, n, by the equation: N= 10n + 120
(a) Illustrate this relation by plotting a graph of N against n for 0 ≤ n ≤ 20.
(b) Hence, or otherwise, calculate the number of
(i) employees when the company has 14 cafes;
(ii) cafes when the company employs 190 people.
(c) State the values of the slope and intercept of the graph and give an interpretation.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
