The slope of the line that passes through two points is

(the difference in 'y') divided by (the difference in 'x').

The two points are:  (3, -4) and (5, -7)

The difference in 'y' is . . . (-7) - (-4) = -3

The difference in 'x' is . . . (5) - (3) = 2

The slope of the line through those two points is (-3) / (2) .

That's the 3rd choice on the list.

true

step-by-step explanation:

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.
