Recall that two lines are perpendicular if the product of their slopes is equal to -1.

Now, notice that the equations of the lines are in slope-intercept form:


y=mx+b,

where m is the slope of the line.

Therefore, the slopes of the lines are:


7,\text{ and }(1)/(7).

The product of the above numbers is:


1.

Therefore, the lines are not perpendicular.

Answer: False.
