Final answer:
To verify that two lines are parallel, compare their slopes (m and n). If the lines are parallel, their slopes will be equal. Solve the equation m = n to find the value of x.
Step-by-step explanation:
To verify that two lines are parallel, we need to compare their slopes. So let's assume that the equation of line m is y = mx + b, and the equation of line n is y = nx + c.
If the lines are parallel, then their slopes, m and n, will be equal. So set m = n.
Solve the equation to find the value of x that satisfies the condition m = n.
