A line passes through the point (-4,9) and has a slope of -3/2
Write an equation in point-slope form for this line.

y - 9 = (-3/2) (x - (-4))

Step-by-step explanation:

We can use the formula y-y1 = m(x-x1)

Where (x1,y1) are (-4, 9) and m = -3/2. Plug in the values and we get

y - 9 = (-3/2) (x - (-4))

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.
