Q. Which describes the system of equations below?\newliney=19x3y = \frac{1}{9}x - 3\newliney=19x3y = \frac{1}{9}x - 3\newlineChoices:\newline(A)consistent and dependent\newline(B)inconsistent\newline(C)consistent and independent
  1. Equations and Slopes: We have the system of equations:\newliney=19x3y = \frac{1}{9}x - 3\newliney=19x3y = \frac{1}{9}x - 3\newlineFirst, we need to compare the slopes of both equations.\newlineIn y=19x3y = \frac{1}{9}x - 3, the slope is 19\frac{1}{9}.\newlineIn y=19x3y = \frac{1}{9}x - 3, the slope is also 19\frac{1}{9}.\newlineSince the slopes are the same, we can say that the lines are parallel or coincident.
  2. Y-Intercepts Comparison: Next, we compare the y-intercepts of both equations.\newlineIn y=19x3y = \frac{1}{9}x - 3, the y-intercept is 3-3.\newlineIn y=19x3y = \frac{1}{9}x - 3, the y-intercept is also 3-3.\newlineSince the y-intercepts are the same, we can say that the lines are coincident, meaning they lie on top of each other.
  3. Conclusion: Since both the slope and yy-intercept of the two equations are the same, the lines represented by these equations are the same line. Therefore, every point on one line is also on the other line, which means the system has an infinite number of solutions.\newlineThe system of equations is consistent because there are solutions, and it is dependent because the equations represent the same line.
