10. Given the two equations below, determine which statement best describes the graph of the equations:

y = 1/6x + 7
y = 1/6x + 16

A The two lines given by the above equations are perpendicular.
B The two lines given by the above equations are parallel.
C The two lines given by the above equations coincide.
D The two lines given by the above equations intersect (but are not perpendicular).

Answer 1

both have 1/6, which means parallel ... B

Answer 2

for parallel lines value of c and k will only vary the co-eff of x and y reamain the same
