Note that two lines are perpendicular if the slope of one of the line is negative reciprocal of the other line's slope. The formula that express the relationship of the slopes of perpendicular lines is:

  `m_2= -1/ m_1`

So to solve , determine the slope of the given line. To do so, express the equation in slope-intercept form y=mx + b.

`x-7y=5`

`-7y=-x + 5`

`y = (- x + 5)...
