What is the equation of the line in standard form perpendicular to 7x-9y = -35 through (4, -7)?
To get the equation, you will have to get the inverse of the first equation. That is, 9y/7=7x/9+35/9. Y=7x/9+35/9. To find the m of the other equation, -7=9x/7-c and this will give you 12 1/7=c. the equation is Y=9x/7+ 12 1/7.
