triangle efg has vertices e(–3, 4), f(–5, –1), and g(1, 1). the triangle is translated so that the coordinates of the image are e’(–1, 0), f’(–3, –5), and g’(3, –3).

which rule was used to translate the image?

t4, –4(x, y)
t–4, –4(x, y)
t2, –4(x, y)
t–2, –4(x, y)

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
