<span>The coordinates of the midpoint of EF is ((xE + xF)/2, (yE + yF)/2)
The third option is the correct answer.
</span>
For
ax+by=c
slope=-a/b
perpendiculare lines have slopes that multiply to -1
so
2x+3y=9
slope=-2/3
-2/3 times what=-1
what=3/2
point slope form
the equation of a line that passes through the point (x1,y1) and the slope is m is
y-y1=m(x-x1)
slope=3/2
point i (8,5)
equation is
y-5=3/2(x-8)
converted to standard form
2y-10=3x-24
-3x+2y=-14
3x-2y=14
