Determine the equation for the line of best fit in slope intercept form.

Include the two points you used to find the slope.

Verify your equation is correct by substituting a given point on the line into your equation.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
