Answer:
The slope that is perpendicular to the line will be:

Step-by-step explanation:
Given the equation

We know that
is the slope-intercept form of a line where m is the slope and b is the y-intercept.
So, writing the equation in the slope-intercept form


here
∵
As we know that for perpendicular lines, one slope is the negative reciprocal of the other.
Therefore, the slope that is perpendicular to the line will be:

(2 - 7z)(2 + 7z)
= (2)^2 - (7z)^2
= 4 - 49z^2
