what are the domain and the range of the relation?
{(−9, 7), (−4, 3), (−1, −6), (2, −8), (5, 12), (10, 11)}
choose exactly two answers that are correct.
a. domain: {−8, −6, 3, 7, 11, 12}
b. domain: {−9, −4, −1, 2, 5, 10}
c. range: {−9, −4, −1, 2, 5, 10}
d. range: {−8, −6, 3, 7, 11, 12}

Domain is the "x" value.

X values are {-9, -4, -1, 2, 5, 10}. That means, this is the domain.

Range is the "y" value.
Y values are {7, 3, -6, -8, 12, 11}. 
The range ise {-8, -6, 3, 7, 11, 12}. 

Answers are B and D.

All points to the left of zero on a horizontal number line are negative. a number line is a picture of a graduated straight line that serves as abstraction for real numbers. this number line can be extended to the left to represent numbers which are smaller than 0. such numbers are called negative numbersmark me brainliest
