The cost of soup, s, varies directly with the number of cans, c. when c is 4, the cost is 3$. which graph represents the cost of soup?

Here,

s represents the cost of soup and c represents the number of can,

Also, s varies directly with c,

⇒ s ∝ c

⇒ s = kc -----(1)

Where, k is the proportionality constant,

Given, when c = 4, s = 3,

From equation (1),

Again from equation (1),

Let x-axis represents the number of can and y-axis represents the cost of soup,

For graphing :

is a straight line

Where, s ≥ 0 and c ≥ 0 ( cost and number of cans can not be negative )

When, c = 0, s = 0,

When c = 4,

When c = 8,

When c = 16,

Thus, the line  is passing from the points (0,0), (4,3), (8,6) and (16,12).
