Final answer:
The set of equations given have no solution.
Step-by-step explanation:
The set of equations given are as follows:
Equation C: y = 6x + 9
Equation D: y = 6x + 2
To determine the solution to this set of equations, we can compare the equations and observe that the slope of both equations is the same, which is 6. However, the y-intercepts are different, with equation C having a y-intercept of 9 and equation D having a y-intercept of 2.
Since the slope is the same but the y-intercepts are different, the lines represented by these equations are parallel. As a result, there is no solution to this set of equations.
