What is the domain of the relation? {(0, –1), (1, –2), (1, 0), (1, 2), (2, 1)} {a, b, c, d, e} {0, 1, 2} {–2, –1, 0, 1, 2}

The domain is the set of X values, which are the first number in each set of parenthesis. If there is more than one identical value, you don't need to list them all, just once.

{(0, –1), (1, –2), (1, 0), (1, 2), (2, 1)}

The X values are 0 , 1 , 1, 1, 2

There are three 1's, but it only needs to be listed once.

The domains are {0, 1, 2}

dont think so

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
