Look at this number line. which expression has a negative value?
a. a-b
b. a+b
c. a-2
d. b-2

D. b - 2

Step-by-step explanation:

First, we read the values of a and b from the number line.

a = 2

b = -1

Now we evaluate each expression.

A. a - b = 2 - (-1) = 2 + 1 = 3 positive, not negative

B. a + b = 2 + (-1) = 2 - 1 = 1 positive, not negative

C. a - 2 = 2 - 2 = 0 zero, not negative

D. b - 2 = -1 - 2 = -3 negative

D. b - 2

answer: '

the distance between points l and m

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
