Answer:
The two lines are neither parallel nor perpendicular
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope of the line and b is the y intercept of the line
Now, we express the two given equations in this form
We have this as;
7y = x + 5
y = 1/7(x) + 5/7
For the second equation, we have;
y = 7x - 4; this is already expressed
the slope of the first line is 1/7
the slope of the second line is 7
when two lines are parallel, their slopes are equal
when two lines are perpendicular, the product of their slopes is -1
As we can see, both cases does not occur in this system of equations
So, we can conclude that both lines are neither parallel nor perpendicular
