Answer 2

\[\frac{y_2-y_1}{x_2-x_1}\]

Answer 3

no it didnt thank you though

Answer 4

baseball just enter the points in that formula above
\[x_1=4
\\y_1=10
\\x_2=6
\\y_2=15\]

Answer 5

So its D ?

Answer 6

@myininaya ?

Answer 7

well it says y is in miles and x is in minutes

Answer 8

didn't we have y's on top?

Answer 9

ya i also think it is D!

Answer 10

^^^

Answer 11

It isn't D.

Answer 12

C ? @myininaya

Answer 13

we have change of y /change of x
and y is in miles
while x is in minutes
so miles should be over minutes

Answer 14

A @ myininaya

Answer 15

what know you just said we had 2.5
i'm telling you what the units should be

Answer 16

i dont get it

Answer 17

you did the calculation and you got 2.5
you did that by calculating change of y over change of x
the top had units miles while the bottom had units minutes
that is miles per minutes since miles is on top while minutes is on bottom

Answer 18

So it is C

Answer 19

\[\frac{15 miles -10 miles}{6 \min-4 \min}=\frac{5 miles}{2 \min} =2.5 \frac{miles}{\min}\]
yes you read this as 2.5 miles per min

Answer 20

thank you
