2-3 more questions to go :)

Solution given:

now

slope [m]=

let's find the slope of line passing through the given points :

a - base

b - exponent

so,

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.
