Giovanna can ride her bike 1.5 mi every 5 min.
How many miles can she ride her bike in 24 min?
miles
OpenStudy (anonymous):
\[\frac{ 1.5 }{ 5 }=\frac{ ? }{ 24 }\]
Can you solve it now?
OpenStudy (anonymous):
umm not really
OpenStudy (anonymous):
Because 24 is in the denominator, multiply both side by 24
OpenStudy (anonymous):
120

What are they? I am ready
OpenStudy (anonymous):
ok ima put it up
OpenStudy (anonymous):
OpenStudy (anonymous):
there it is
OpenStudy (anonymous):
\[slope=\frac{ rise }{ run }\]
What do you think?

OpenStudy (anonymous):
idk
OpenStudy (anonymous):
Well when x runs from 6 to 18, y rises from 2 to 6. So \[Slope=\frac{ 12 }{ 4 }=3\]
OpenStudy (anonymous):
oh thx
OpenStudy (anonymous):
No problem
OpenStudy (anonymous):
ima put next up ok

Sure.

OpenStudy (anonymous):
there it is u get is
OpenStudy (anonymous):
How about taking the y of the first and the y of the second coordinate then form (x,y)
For example, (3,2) and (6,4) --> (6,2)
OpenStudy (anonymous):
so i subtract

OpenStudy (anonymous):
i need the answers and then u can explain it plz
OpenStudy (anonymous):
No take y of the first one, which is 2.
Then take x of the second one, which is 6
x = 6, y = 2 ---> (6,2)
OpenStudy (anonymous):
huh how for the first one 3,2 and 6,4
OpenStudy (anonymous):
how would u find the answer
OpenStudy (anonymous):
The way I did, I think the answer for the first one is C. (6,2)
