Question 832015: Find an equation of the line that passes through the point (4,2) and is perpendicular to the line 4x+3y=0
Answer by erica65404(394) (Show Source): You can put this solution on YOUR website!
The first you need to do, is find the slope of the given line. Solve the equation for y.

the slope for this line is
Now we need to find a slope that is perpendicular. Take the recriprocal and multiply it by -1.
's reciprocal is and multiply it by -1 to get a slope of .

Now we have as the beginning of the perpendicular line. We still need to find b.
They give you the point (4,2), plug in the x and y values into the equation and solve for b.

now the final equation is
