Question 5350
perpendicular lines have slopes that when multiplied together = -1
so convert this line to y=mx+b formula 
x+2y=2
2y=-2x+2
The slope is -2

So I know that the perpendicular line will have a slope of {{{1/2}}}, because {{{(1/2)*-2=-1}}}
So using y=mx+b and the point I have (8,17), I substitute my point into the equation:
{{{y=mx+b}}}
{{{17=(1/2)(8)+b}}}
{{{17=4+b}}}
{{{13=b}}}
Now I can use my slope and my intercept to put into a formula:
{{{y=(1/2)x+13}}}
