How many solutions does the system of equations below have? y = –2x + 9/7 y = –2x + 7/9 Choices: (A)no solution (B)one solution (C)infinitely many solutions

Slope Analysis: System of equations: y = –2x + 9/7 y = –2x + 7/9 Are the slopes same or different? Slope of first equation: -2 Slope of second equation: -2 Slopes of the equations are the same.Y-Intercept Comparison: System of equations: y = –2x + 9/7 y = –2x + 7/9 Are the y-intercepts same or different? y-intercept of first equation: 9/7 y-intercept of second equation: 7/9 y-intercepts of the equations are different.Number of Solutions: System of equations: y = –2x + 9/7 y = –2x + 7/9 Determine the number of solutions to the system of equations. The system of equations has the same slope but different y-intercepts. The system of equations has no solution because they are parallel lines that never intersect.
