Answer:

y= 3x + 7

Step-by-step 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:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

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

(0, 7)

(1, 10)

=> m = [tex]\frac{10-7}{1-0} = \frac{3}{1} =3[/tex]

=> 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.
