Parallel lines share the same slope, so the slope of the parallel line in this case must be .
Point-slope form is , where is the slope and is any known point on the line.
Plug in the values.
Simplify and distribute.
Subtract 1 from both sides.
Eccentricity = foci / half the length of the major axis
= 3.5 / 14 = 1/4
Answer:
A
Step-by-step explanation:
