How many solutions does the system of equations below have? y = –9x + 9/4 y = –9x + 6/5 Choices: (A)no solution (B)one solution (C)infinitely many solutions

Analyze Slopes: Analyze the slopes of both equations. The slope of the first equation (y = –9x + 9/4) is -9. The slope of the second equation (y = –9x + 6/5) is also -9. Since both slopes are equal, the lines are either parallel or the same line.Compare Y-Intercepts: Compare the y-intercepts of both equations. The y-intercept of the first equation is 9/4. The y-intercept of the second equation is 6/5. Since the y-intercepts are different, the lines are parallel and do not intersect.Determine Solutions: Determine the number of solutions. Parallel lines never intersect, so there are no points that satisfy both equations simultaneously. Therefore, the system of equations has no solution.
