You can put this solution on YOUR website! What is the equation for the line is perpendicular to 7x + 8y = 2 and passes through (4,2)
----
Find the slope of the given line::
y = (-7/8)x + 1/4
slope = -7/8
-------
Slope of each line perpendicular to the given line = 8/7
------------
Form:: y = mx + b
Solve for "b"::
2 = (8/7)4 + b
-----
14/7 = 32/7 + b
b = -18/7
-------
Equation:
y = (8/7)x - (18/7)
