Concept explainers
Find which pair of equation may be represented by the graphs.
Answer to Problem 112E
The pair of equation A will be the right for the given graph, that is,
Explanation of Solution
Given:
It is given in the question that there is a graph and the four equations are given:
Concept Used:
In this , use the concept of slope − intercept form and also know to analysis of graph and finding the answer.
Calculation:
It will probably be easiest to quickly re − arrange the equations into the usual slope − intercept form.
From GRAPH , it is found out that slopes need to be negative reciprocals.
B can’t be right because the lines seems more steep than
And D can’t be right because the lines are not perpendicular .
But Ccannot be right because both lines would be decreasing left to right.
A can be right becausetheir both slopes have reciprocal of each another.
Conclusion:
The equation A is right for graph.
