Answer:
vector equation:
<x2+7, y2-2> = t <-7,2>
3 variable parametric equations:
x= -7t + 7
y= 2t + (-2)
Step-by-step explanation:
given the vector of a = <-7,2> we know that a1 will be -7 and a2 will be 2.
The point (1,5) gives us our x1 and y1 to plug into the vector equation. So we plug it into <x2 - x1, y2 - y1> = t <a1, a2> and get <x2+7, y2-2> = t <-7,2>. We then use the same x1, y1, a1, and a2 and plug into the 3 variable parametric equations or x= x1+ ta1 and y= y1 + ta2 to get working equations of x = -7t + 7 and y= 2t + (-2).
Answer:
x = -7t + 7 and y= 2t + (-2).
