Which of the following statements uses the commutative property of addition?

2 + (3 + 4) = (2 + 3) + 4
2 + (3 + 4) = (2 + 3) + (2 + 4)
2 + (3 + 4) = 2 + (4 + 3)

The correct answer is:

2 + (3 + 4) = 2 + (4 + 3)

Explanation:

The commutative property of addition tells us that the two addends, or numbers being added, can be "flipped around" the addition symbol.  The only problem in which this occurs is 2 + (3 + 4) = 2 + (4 + 3) .

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

its 50 miles away from the starting point
