Question

Data were collected and plotted on a scatter plot.

A scatter plot contains the ordered pairs 0,0.5 and 1,2 and 1.5,3.5 and 3,2.5 and 3,4.5 and 4,7 and 4.5,5 and 5,6 and 5,11 and 5.5,8 and 5.5,14 and 6,9 and 6.5,11 and 7,13 and 7,15.

Which of the following is the most appropriate equation to model the data?

ŷ = 1.1x + 1.467
ŷ = 1.467x + 1.1
ŷ = 1.1(1.467)x
ŷ = 1.467(1.1)x

Answer 1

Working on it

Answer 2

alrighty so as x increases, y increases which means we're looking for something positive

Answer 3

the scatterplot is kind of curving so we know it's not a line which means we can cross out the choices that look like a line, so the ones that look like y = mx + b
and that leaves us with the last two

Answer 4

right

Answer 5

Well we know the y intercept is going to be around 0.5 since that's what pairs with 0 so let's choose the lesser of the two which is y=1.1(1.467)x

Answer 6

lets see if these are correct..
