Write a vector equation of the line that passes through P(4, 7) and is parallel to a = (3, 8).
A. (x-8, y-15) = t(9 8)
B. (x-4, y-7) = t(3, 8)
C. (x+10, y+9) = t(8, -4)
D. (x+15, y+14) = t(8, 9)

B

Step-by-step explanation:

(x,y) = P + (a)t

(x,y) = (4,7) + t(3,8)

(x,y) - (4,7) = t(3,8)

(x-4, y-7) = t(3,8)

step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
