Answer 1

Answer:

The answer to your question is below

Step-by-step explanation:

Part A.

               -3x + 7y = 13

Solve the equation for "y"

               7y = 3x + 13

                y = $\frac{3}{7} x + 13$

Part B.

Two lines are parallel if their slopes are the same

Two lines are perpendicular if their slope are opposite reciprocals

Slope of the first line = $\frac{3}{7}$

Slope of the second line = $\frac{3}{7}$

Conclusion: the lines are parallel because their slopes are the same.
