Question

Will Medal! Linear Equations Question http://screenpresso.com/=EaDZe
That's the portfolio since I messed up in the beginning where I tried to start.

Answer 1

speed = x-axis
Distance = y-axis
there are two coordinates
for Rabbit when speed =30 distance = 1.5
(30,1.5)
can you write the coordinate for cheetah :D?

Answer 2

Oh wait, I thought I have to put it into an equation? Or am I getting to far ahead of myself?

Answer 3

I think you should just post the question since I don't know what you're meant to find.

Answer 4

It's a portfolio.

Answer 5

that's right you need two order pair to find the slope and then y-intercept.

Answer 6

Oh, so (70,3.0) for cheetah.

Answer 7

yes (30,1.5)(70 ,3)
use the slope formula \[m=\frac{y_2-y_1}{x_2-x_1}\]

Answer 8

May I ask what "m" is representing?

Answer 9

y=mx+b is slope intercept form( linear equation)
where m is the slope and b is y-intercept

Answer 10

Why would you find the slope between two points which are on different graphs?

Answer 11

But I need to put them in one equation, that's where I'm stuck.

Answer 12

That makes no sense.

Answer 13

then.. how would we find the equation ?
there is no other information that we can use...

Answer 14

You have two different graphs. Making one equation for them is nonsense.

Answer 16

Take a screenshot.

Answer 18

Maybe the better question is, am I even doing it right?

Answer 19

Ah, that is entirely different to the two graphs you posted... what you've done so far doesn't seem useful. You need to make equations that depend on time. Using distance = speed*time

Answer 20

#3 *write a system of two linear equation*

Answer 21

So as far as time goes... I need to base it off time instead?

Answer 22

Eg for the cheetah: d = 70t

For the rabbit: d = 35t

But since the cheetah runs faster, you'll need to give the rabbit a headstart, put him a certain distance ahead. eg. d = 35t + 50, ie the rabbit is getting a 50 mile headstart.

Answer 23

Agent0smith had stated the following in a PM:

For 3 miles and 1.5 miles you could make the cheetah's equation d = 70t

Rabbit's equation: d=35t + 1.5 (which is like he's starting 1.5 miles ahead (Or divide by two once working out the rest of the question).

@mathmale

I am still a bit stuck.

Answer 24

So it'd be rabbit: 1.5 = 35t
And cheetah 3.0 =70t ?

Answer 25

Hey lauren i medaled you bye <3

Answer 26

Nevermind, I got it. Thanks for your help guys!
