Solve both equations for y:
Set the expressions equal to each other:
So, for every nonzero number a the system of equations has
one solution.
Answer:
B. It is decreasing.
Step-by-step explanation:
The X value is the sideways one, and the direction of the line in between the two points listed is going downwards. The value of the line in the graph is decreasing.
One of the most common choices is the logarithmic scale, which is a representation of the positive numbers on a line, such that the distance of two points is the unit length, if the ratio of the represented numbers has a fixed value, typically 10.
