Which numbers are in the domain of the following function?
2 answers:
As we know that a relation is a set of ordered pairs.
Also we know that a function is a relation in which no two different ordered pairs have the same first coordinate.
Hence the given ordered pair represents a function.
Here in the ordered pair the x-coordinate represents the domain of the function, while the y-coordinate represents the range of the function.
Hence the domain of the function represented by the above ordered pair is

Answer:
y = 1.5x + 1.5
Step-by-step explanation:
First, plot 2x + 3y = 15 on a graph. Then plot (1,3) on a graph. After that, draw a line that passes through (1,3) and forms 90 degrees angles with 2x + 3y = 15. Then find the equation of that line by finding the y-intercept (0, 1.5). Then head up to the intersection point (1.6153846153846, 3.9230769230769). Subtract 1.5 from y. (2.4230769230769) Then divide by 1.5 (1.6153846153846). Reverse the operations you just did (in reverse order) to get the equation y = 1.5x + 1.5.
(I don't know how to explain this too well. Here's a graph to make more sense of it.)
