Answer 1

anyone

Answer 2

Recall that
Distance = Rate * Time
So:
\[\frac{ Distance }{ Time }=Rate\]
What is the Rate in Question 5? @ladydy

Answer 3

im bad at math i dont know

Answer 4

For question 6:
Recall that:
\[Slope=\frac{ \Delta Y }{ \Delta X }\]

Find 2 points on the graph... & count

Answer 5

For question 5....

If one of the points on the graph is (4 hours, 186 miles)
What is
\[Rate(mph)=\frac{ 186miles }{ 4hours }\]

Answer 6

For 7 & 8....
Do you know how to find the linear slope between two points?
@ladydy

Answer 7

no

Answer 8

\[m=\frac{ y2-y1 }{ x2-x1 }\]

Answer 9

thanks

Answer 10

Assign pairs to the set of points given....
For example
(x1,y1)
(x2,y2)
& plug in... you get m (: aka slope
& NP what did you get for 5 & 6? :D

Answer 11

for 5 if you mean DIVIDE 186 by 4 i got 46 is that right

Answer 12

Yep :D .... Rate is 46mph

Answer 13

for 6 im still not sure but i think it's 5??!

Answer 14

oh yay thanks!

Answer 15

Hmm... welll recall that
