Which statement is true concerning the graph of two lines showing the given rates?

Rate 1: 20 ft in 5 s
Rate 2: 18 ft in 3 s

OPTIONS-

A.
The graph with Rate 1 passes through (3, 12).

B.
The graph with Rate 2 passes through (3, 15).

C.
The graph with Rate 1 passes through (8, 2).

D.

Answer 2

Could you expand the question or do you have any options? Because I didn't understand the question

Answer 3

alright :)

Answer 4

A.
The graph with Rate 1 passes through (3, 12).

B.
The graph with Rate 2 passes through (3, 15).

C.
The graph with Rate 1 passes through (8, 2).

D.
The graph with Rate 2 passes through (12, 2).

Answer 5

The equation for the line is y = slope * x
For line 1: The rate or slope is 20 ft for 5s i.e 4ft/s
For line 2: The rate is 6ft/s
Now write the equations and see for the options.
Hope this helps.

Answer 6

I Don't get it :/

Answer 7

Ok
So line 1 is y = 4*x and line 2 is y = 6*x
Put (3,12) and see if this satisfies any equation.

Answer 8

Thanks! Win a Medal!

Answer 9

Both C and D satisfies

Answer 10

If you draw a graph for both of the rates and substitute C and D values, you can see that it satisfies

Answer 11

:/ But I can only pick 1 option

Answer 12

D does not satisfy.

Answer 13

How?

Answer 14

If it were (2,12), then it satisfies line 2.

Answer 15

No. Check it once again you will get 6y=x

Answer 16

The eqn is y = 6x
The point is (12,2)
2 = 6*12 is not true. D cannot be a possibility.

Answer 17

y-y1=y2-y1/x2-x1(x-x1) is the formula i used

Answer 18

But you don't have two points to use this formula..

Answer 19

you can get 2 points 20 ft in 5 s is 4 ft in 1 sec
