Concept explainers
Find which equations may be represented by the graphs shown.(It may be more than one answer).
Answer to Problem 109E
The correct equation for the graph is A,
Explanation of Solution
Given: It is given in the question that the graph is given below and four more equations.
Concept Used:
In this , use the concept of Slope intersept form and analyise the equation and also use the concept of graphical analysis.
Calculation: In this , it has to be done that use slope intersept form to all the equations,
In this,it is seen that the graph has a positive slope, so it need to rearrange the equations to find the ones with a positive slope.Also,the line intersects the y axis above the origin,so it will need to have a positive y − intersept.
By seeing the above fact the correct equation is A.
Conclusion:
The correct equation is A.
