Question

Find the distance of the point (−3,−9) from the line through (−3,3) which points in the direction of −2 I+10 J.
?????

Answer 1

-2i +10j represents a vector (through 0,0) and your (-3,3) will be parallel to it (ie the "slope" will be the same).

So use the slope and point to get the line and then as usual.....

Answer 2

usual ?!

Answer 3

The way you would with normal lines (i am assuming that u must be familiar with this if u are now doing vector versions).

Answer 4

oh yeah thanks
