from the line y=2x-10 find the equation of the line that is perpendicular to this line and goes through the point (9,-5)
creativ13 [48]
2 is the slope so the slope perpendicular to that is -1/2 (negative reciprocal)
-5=-1/2(9)  9*-1/2=-4.5 and -4.5 - 0.5 = -5 so the equation for the line is y=-1/2x -0.5

<u> Equation:</u>

x(x      -     5)     +     3(x     +     5)

<u>Steps:</u>

x(x      -     5)     +     3(x     +     5)

<u>Expand:</u>

x(x     -     5 ):           x^2      -    5x

x^2    -    5x     +   3(x      +     5)

<u>Expand:</u>

3(x     +    5):        3x   +    15

x^2     -     5x     +     3x       +     15

<u>Add Similar Elements:   </u>  

-5x      +    3x    

=         -2x

Answer        x^2    -     2x      +    15    Doesn't Factor






Hope that helps!!!                                  : )
