Q. How many solutions does the system of equations below have?\newliney=3x+45y = 3x + \frac{4}{5}\newliney=3x+72y = 3x + \frac{7}{2}\newlineChoices:\newline(A)no solution\newline(B)one solution\newline(C)infinitely many solutions
  1. Analyze slopes: Analyze the slopes of both equations.\newlineThe slope of the first equation y=3x+45y = 3x + \frac{4}{5} is 33.\newlineThe slope of the second equation y=3x+72y = 3x + \frac{7}{2} is also 33.\newlineSince both slopes are equal, the lines are either parallel or the same line.
  2. Compare y-intercepts: Compare the y-intercepts of both equations.\newlineThe y-intercept of the first equation is 45\frac{4}{5}.\newlineThe y-intercept of the second equation is 72\frac{7}{2}.\newlineSince the y-intercepts are different, the lines are parallel and do not intersect.
  3. Determine solutions: Determine the number of solutions.\newlineParallel lines never intersect, so there are no points that satisfy both equations simultaneously.\newlineTherefore, the system of equations has no solution.
