Identify the slope and y-intercept (if they exist) 5x - 9y = -1

What is the slope?
What is the y-intercept?

slope : 5/9

y int : 1/9

(I think..)

Step-by-step explanation:

5x - 9y = -1

-5x. -5x

-9y = -5x - 1

(divide by -9)

y = 5/9x + 1/9

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.

what is the original number? you forgot to add it.
