Question

please help question is in the picture.

Answer 1

The number in front of the x on each answer if the slope. Would you know how to find that looking at this graph?

Answer 2

You just need to plug in the x and y values until you find the values that satisfy the equation

Answer 3

For example, option A.

y=0.014x+49.15

1.55=0.014(50)+49.15

If you solve this, is it true or false?

Answer 4

This is harder than it looks

Answer 5

Not really, it is just plugging in values for the variables, and then solving the equation.

Answer 6

Ok but i am not a mathlete

Answer 7

Neither am I, I bought that title.

Answer 8

So, @KatyKatie, is it true or false?

Answer 9

Really

Answer 10

Yeah, pretty simple if answer choice are given

Answer 11

How do you but the title

Answer 12

Yup, you just earn enough medal and then buy whatever title you want.

Answer 13

I think i have 2 medals

Answer 14

How much can i get for that

Answer 15

Well, 498 more, and you could be a mathlete.

Answer 16

What

Answer 17

But, really. @KatyKatie, do you have an answer for me?

Answer 18

sorry i was doing something it's false

Answer 19

Yes, so could you try the same thing with option C?

Answer 20

ok

Answer 21

Ok, just let me know when.

Answer 22

Yes, therefore, C is your answer.

Answer 23

thank so much for your help again

Answer 24

No problem, and if you have any more questions about this problem or similar, just let me know.

Answer 25

ok

Answer 26

testing 1point in general is not sufficient. since 2 different lines can cross at the same point you would have to find an equation that satisifies 2 points

Answer 27

True, I forgot to mention that I guess, but I had done it before just to verify my answer, but yes a good point indeed.

Answer 28

one way to narrow the work ..

only 2 slopes are given as options.

test out a point: (a,b)

y = m(x-a)+b

for each slope m and see if you only get one option.

Answer 29

.014(-50)+1.55 = .85 as the y intercept

58.8(-50)+1.55 = -2938.45, which isnt an option ... so yeah
