Q. How many solutions does the system of equations below have?y=−72x−1y=−72x−1Choices:(A)no solution(B)one solution(C)infinitely many solutions
Analyze System of Equations: Analyze the given system of equations to determine how many solutions it has.The system of equations is:y=7−2x−1y=7−2x−1Since both equations are identical, every point on the line y=7−2x−1 is a solution to the system.
Determine Number of Solutions: Determine the number of solutions for a system where both equations are the same.When two equations are identical, they represent the same line. Therefore, any point that lies on this line is a solution to both equations. This means that there are infinitely many points that satisfy both equations.
Choose Correct Answer: Choose the correct answer from the given choices based on the analysis.Since there are infinitely many solutions, the correct choice is:(C) infinitely many solutions
