Answer:
Graph the line y = -2.
Step-by-step explanation:
A line with zero slope is a horizontal line. Find (0, -2) on the y-axis and draw a horizontal line through it. This will fully address this question.
Answer:
s = (r + p)/t
Step-by-step explanation:
r + p = st
s = (r + p)/t
Answer:
#6
Domain = {6, 8, 9, 11}
This represents the ages of the students surveyed.
Range = {0, 1, 2, 3}
The range is the possible number of pets that the students may have.
This is not a function because in functions, each x-value can only have one y-value. The x-value, age 11, has two possible y-values, number of pets.
#7
Domain = {1, 2, 3, 4, 5}
This represents the time passed in hours that the distance was measured
Range = {50, 100, 150, 200}
This represents the possible distances in miles that were measured.
This is a function. Each x-value only have one y-value. Each hour only has one possible distance.
Explanation:
The domain is used to state all of the possible x-values in a set of data.
The range is used to state all of the possible y-values in a set of data.
The x-values may also be called independent variables, and the y-values may be called dependent variables. The y-values change depending on what "x" is.
A set of data is a function when each and every x-value only has one y-value.
It is still a function if y-values have more than one x-value. (On a graph, it look like a horizontal line, like in question 7).

Not necessarily. Triangle ABC could be isosceles. Since the problem gives no further information about the third side, you cannot conclude definitely that ABC is equilateral.
