Question 27107
You were actually on the right track, very good.
The one mistake you did when figuring out the slope;
The fromula;
m={{{(y2-y1)/(x2-x1)}}}
When you subtract the y2-y1 and x2-x1,
you will actutally add;
{{{(2-(-3))/(2-(-3))}}}
youforgot to change the sign of the -3 to +3, that would make you adding;
{{{(2+3)/(2+3)}}}
{{{5/5}}}=1
So the slope of a parallel line would be 1, and then a perpendicular line would be -1;
You were doing great, at least you remembered the formula, you made the mistake SO MANY students make, watch those signs!!!
Good Luck on your test
