Answer:
Step-by-step explanation:
The leftmost line segment has a slope of -2 and (-1,-1) is a point on the line.
Equation: y = -2x-3
middle line segment has a slope of 0 and y-intercept of -2.
Equation: y = -2
The rightmost line segment has a slope of 1.5. (5,0) is a point on the line.
y = 1.5(x-5) = 1.5x-7.5
Answer:
Depending on how the input of each function defined,
- The first choice
, - The third choice

- The fourth choice

might be functions.
Step-by-step explanation:
A function between two sets (domain and range) should
- be defined for all elements in the domain, and
- map each element from the domain to exactly one element in the range.
The second choice can't be a function since the element
from the domain is mapped to more than one element in the range.
Keep in mind that a function should be defined for all elements in its domain. For the first relation to be a function, its domain needs to be
. Similarly, the domain for the third and fourth relations should be
and 
It is 12 - 2/3 = 18, then solve :)
hope that helps :D
