step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

it would be 3 ÷by 6 because the number on each side

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,
