Determine if each point P is on the line [x,y] = [2,-3] + t[4,7]

a) P(-2,-10)

b) P(6,5)

c) p(10,14)

d) P(4, 0.5)

Answers: Yes, No, No, Yes

We just learned this today and I'm not sure of the difference between vector r and vector "r not" from r = r0 + tm. I'm not sure where to substitute the given points.
