Q. Which describes the system of equations below?\newliney=52x+9y = \frac{5}{2}x + 9\newliney=52x+9y = \frac{5}{2}x + 9\newlineChoices:\newline(A)consistent and independent\newline(B)consistent and dependent\newline(C)inconsistent
  1. Compare slopes: We have the system of equations:\newliney = (52)x+9(\frac{5}{2})x + 9\newliney = (52)x+9(\frac{5}{2})x + 9\newlineFirst, we need to compare the slopes of both equations.\newlineIn y=(52)x+9y = (\frac{5}{2})x + 9, the slope is 52\frac{5}{2}.\newlineIn y=(52)x+9y = (\frac{5}{2})x + 9, the slope is also 52\frac{5}{2}.
  2. Compare y-intercepts: Next, we compare the y-intercepts of both equations.\newlineIn y=52x+9y = \frac{5}{2}x + 9, the y-intercept is 99.\newlineIn y=52x+9y = \frac{5}{2}x + 9, the y-intercept is also 99.
  3. Identical lines: Since both the slopes and yy-intercepts of the two equations are the same, the lines represented by these equations are identical. Therefore, every point on one line is also on the other line, which means the system has an infinite number of solutions.
  4. Choose correct option: Choose the option that correctly describes the given system of equations. Since the lines are identical, the system is consistent (it has at least one solution) and dependent (the equations are essentially the same, so they depend on each other for all their solutions).
