This is 2.
dotty and lionel are making a graph comparing a car's age with its gas
mileage. dotty says the graph should show discrete points because the car's
age is stated in whole numbers of years. lionel says they should make a
continuous line because age increases gradually, like time. which student do
you agree with and why?

Lionel should be the correct answer.

Step-by-step explanation: When you are talking about age, that means time. Time is continuous, never stopping or slowing down for anyone. Therefore the graph should be continuous.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

yes. we do proportions in probabilities.
