Find the vector and parametric equations for this line: goes through (7,5) with inclination 45º.

Ok, we'll give it a go....  So our line (in ordinary slope-intercept form) is y=x-2.  We together on this so far?

anonymous · Answer

Parameterize x=t, y=t-2.  Not very imaginative, but I think it works for any value of x,y, and  t.

anonymous · Answer

If I want to put it into a vector, you could look at it like$$V(vector)=t *i(unit vector)+(t-2)*j(unitvector)$$I'm sorry, my mastery of LATEX is just about non-existent.

anonymous · Answer

The V(vector) is a function of parameter t.

Hope I was helpful.

x=7-7t
y=5-7t
Vector Equation:  (7,5)+(-7,-7)t
