Find an equation of the line satisfying the given conditions.
Through (6,4); perpendicular to 9x+4y=70
For two perpendicular lines the product of their slope will be -1.
In the line write the equation in the form where m is the slope of the line.
on comparing this equation with standard equation we get slope
Therefore slope of other line m2 , we know
it is given that it passes through point (6,4) So it should satisfy in the line equation.
the equation of second line becomes
giving point , and
we get y intercept ,
so we can write line equation as ,
or or
