Question

Which set of parametric equations represents the following line or conic?
Line: passes through (1,9) and (-6,-1)
Use x=x1+t(x2-x1) and y=y1+t(y2-y1)

Answer 1

7y=10x+53

Answer 2

x = - 7t + 1
y = - 10t + 9




B.
x = - 7t + 1
y = 10t + 9




C.
x = - 7t + - 1
y = - 10t - 9




D.
x = - 10t + 9
y = - 7t + 1




E.
x = - 10t - 9
y = - 7t - 1
