Slope is 5, and (5,3) is on the line
The equation of the line is y=___

y = 5x - 22

Step-by-step explanation:

In this question, we have to find the equation of the line.

We know that the slope is 5 and passes through (5, 3) on the graph.

We know that our equation must be in slope-intercept form: y = mx + b

To find our y-intercept, or "b", we would plug in our given information and solve for b.

Solve for b:

3 = 5(5) + b

3 = 25 + b

Subtract 25 from both sides.

-22 = b

This means that our y-intercept is -22. We can now make our equation with our new information:

y = 5x - 22

The equation of the line is y = 5x - 22

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.

a) 7x=7
