Question

The graph represents amount of phosporus required to produce a fertilizer.

Slope of the above graph is

• A. 0.2
• B. 2
• C. 1

Answer 1

The correct option is A 0.2


From the given graph, let us consider the points (1,0.2) and (3,0.6)

$\therefore \text{Slope}=\frac{\text{Rise}}{\text{Run}}$
$=\frac{0.6-0.2}{3-1}=\frac{0.4}{2}=0.2$

Hence, slope of the given graph is 0.2.
