The graph below shows a line segment ab:
which of the following equations best represents the line segment ab?
graph of line ab going through ordered pairs negative 1, 5 and 2, negative 4
y = −3x + 2
y = −2x + 1
y = −3x − 2
y = −2x − 1

The correct option is 1.

Step-by-step explanation:

It is given that the line AB, going through ordered pairs (-1,5) and (2,-4).

If a line passing through two points, then the equation of line is

The equation of line AB is

Add 5 both the sides.

Therefore option 1 is correct.

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

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.
