Hint: Use the distance formula:
d= (x2 - 1)2 + (y2 - y.)2

slope = - 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = A (- 1, 2) and (x₂, y₂ ) = B (1, - 2)

m = = = = - 2

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
