The number in front of the x on each answer if the slope. Would you know how to find that looking at this graph?
anonymous
  • anonymous
You just need to plug in the x and y values until you find the values that satisfy the equation

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?
Nerdsarecool

This is harder than it looks
anonymous
  • anonymous
Not really, it is just plugging in values for the variables, and then solving the equation.
Nerdsarecool
  • Nerdsarecool
Ok but i am not a mathlete
anonymous
  • anonymous
Neither am I, I bought that title.
anonymous
  • anonymous
So, @KatyKatie, is it true or false?
Nerdsarecool
  • Nerdsarecool
Really
FortyTheRapper
  • FortyTheRapper
Yeah, pretty simple if answer choice are given
Nerdsarecool
  • Nerdsarecool
How do you but the title
anonymous
  • anonymous
Yup, you just earn enough medal and then buy whatever title you want.
Nerdsarecool
  • Nerdsarecool
I think i have 2 medals
Nerdsarecool
  • Nerdsarecool
How much can i get for that
anonymous
  • anonymous
Well, 498 more, and you could be a mathlete.
Nerdsarecool
  • Nerdsarecool
What
anonymous
  • anonymous
But, really. @KatyKatie, do you have an answer for me?
anonymous
  • anonymous
sorry i was doing something it's false
anonymous
  • anonymous
Yes, so could you try the same thing with option C?
anonymous
  • anonymous
ok
anonymous
  • anonymous
Ok, just let me know when.
anonymous
  • anonymous
Yes, therefore, C is your answer.
anonymous
  • anonymous
thank so much for your help again
anonymous
  • anonymous
No problem, and if you have any more questions about this problem or similar, just let me know.
anonymous
  • anonymous
ok

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
anonymous
  • anonymous
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.
amistre64
  • amistre64
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.
amistre64
  • amistre64
.014(-50)+1.55 = .85 as the y intercept 58.8(-50)+1.55 = -2938.45, which isnt an option ... so yeah
