Q. Which describes the system of equations below?\newliney=49x+3y = -\frac{4}{9}x + 3\newliney=49x+73y = -\frac{4}{9}x + \frac{7}{3}\newlineChoices:\newline(A)consistent and independent\newline(B)inconsistent\newline(C)consistent and dependent
  1. Analyze Slopes: Analyze the slopes of both equations.\newlineThe first equation is y=49x+3y = \frac{-4}{9}x + 3, which has a slope of 49\frac{-4}{9}.\newlineThe second equation is y=49x+73y = \frac{-4}{9}x + \frac{7}{3}, which also has a slope of 49\frac{-4}{9}.\newlineSince both slopes are equal, the lines are either the same line (if they have the same yy-intercept) or parallel lines (if they have different yy-intercepts).
  2. Compare Y-Intercepts: Compare the y-intercepts of both equations.\newlineThe y-intercept of the first equation is 33.\newlineThe y-intercept of the second equation is 73\frac{7}{3}, which is also equal to 33 when converted to a mixed number (since 73=213=3\frac{7}{3} = 2 \frac{1}{3} = 3).\newlineSince both y-intercepts are equal, the lines are the same line, and therefore, every point on one line is also on the other line.
  3. Determine System Type: Determine the type of system based on the slopes and yy-intercepts.\newlineSince the slopes are equal and the yy-intercepts are equal, the system of equations represents the same line. Therefore, the system has an infinite number of solutions, as any solution that works for one equation will also work for the other.\newlineThis means the system is consistent (it has at least one solution) and dependent (the equations are dependent on each other, as they represent the same line).
