Q. Which describes the system of equations below?\newliney=9x+1y = -9x + 1\newliney=9x+1y = -9x + 1\newlineChoices:\newline(A) inconsistent\newline(B) consistent and independent\newline(C) consistent and dependent
  1. Compare Slopes: We have the system of equations:\newliney = 9x+1-9x + 1\newliney = 9x+1-9x + 1\newlineFirst, we need to compare the slopes of both equations.\newlineIn y=9x+1y = -9x + 1, the slope is 9-9.\newlineIn y=9x+1y = -9x + 1, the slope is also 9-9.
  2. Compare Y-Intercepts: Next, we compare the y-intercepts of both equations.\newlineIn y=9x+1y = -9x + 1, the y-intercept is 11.\newlineIn y=9x+1y = -9x + 1, the y-intercept is also 11.
  3. Identical Lines: Since both the slope and yy-intercept of the two equations are the same, the lines they represent are identical. This means that every solution to one equation is also a solution to the other, and they have infinitely many points in common.
  4. Consistent and Dependent: Choose the option which describes the given system of equations. Since the slopes and yy-intercepts are the same, the system of equations is consistent and dependent. This means that there is not just one solution, but an infinite number of solutions because the two equations represent the same line.
