Question

The graph of the line represents the cost of renting a kayak. Write a linear

function in the form y=mx + b to represent the relationship of the total
cost, c, of renting a kayak fort hours

Answer 1

Answer: y=3x + 7

Step-by-step explanation: I did it

Answer 2

y= 3x + 7

Explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

Given the standard form of the line:

y - mx + b where:

• m is the slope
• b is the y-intercept

As we know, the slope can be found with this formula:

`m=(y_2-y_1)/(x_2-x_1)`

From the line, we can choose the two points to find the slope of the equation:

(0, 7)

(1, 10)

=> m =
`(10-7)/(1-0) = (3)/(1) =3`

=> y = 3x + b (1)

Because the line goes through point (0, 7) so we substitute it into (1) to find b, we have:

7 = 3*0 + b

<=> b = 7

Hence, our equation is: y = 3x + 7 represent the relationship of the total

cost, c, of renting a kayak for hours

Hope it will find you well.
