For the first one, substitute the value of x that they give you into the equation
Mehek14
  • Mehek14
like for C, they gave you 3 so solve \(\tt{y=1.3*3}\)

3.9
Mehek14
  • Mehek14
yes so for C, the y coordinate is 3.9
Mehek14
  • Mehek14
for D, you have -6 \(\tt{y=1.3*(-6)}\)

  • AlexandervonHumboldt2
yeah i'm here
Testing123guest
  • Testing123guest
cool give me a sec to answer
Testing123guest

-7.8
AlexandervonHumboldt2
  • AlexandervonHumboldt2
yeah -7.8
Mehek14
  • Mehek14
So Point C (3,3.9) Point D(-6,-7.8)

For the second question, you substitute the answer choices into the equation.
Mehek14
  • Mehek14
so like A (-1,-12) \(\tt{-12=12*(-1)}\) is that true?
Testing123guest
  • Testing123guest
yes it is true
Testing123guest
  • Testing123guest
is there a way we can make this a little bit faster i need to get done soon
Mehek14
  • Mehek14
yea sure
Testing123guest
  • Testing123guest
*soon*
Mehek14
  • Mehek14
But I want to make sure you understand how to solve
Testing123guest
  • Testing123guest
i know i am just on a time crunch
Mehek14
  • Mehek14
So you want answers or how to solve?
Testing123guest
  • Testing123guest
both but faster but its cool no rush
Mehek14
  • Mehek14
ok so it's not B because -1 = 12*(-12) <-- not true C is correct because 12 = 12*1 D is incorrect because 1 = 12*12 <-- not true so the answers to the second question are A and C
Testing123guest
  • Testing123guest
for the second question
Mehek14
  • Mehek14
yes second question
Testing123guest
  • Testing123guest
cool i got that on know
Mehek14
  • Mehek14
third question: slope is -1.5 that means the line is going down so it can't be B or C
Mehek14
  • Mehek14
the correct graph would be A
Testing123guest
  • Testing123guest
cool now this is better
Mehek14
  • Mehek14
ok fourth question: line is going up so positive slope so between A and B the correct answer would be B
Testing123guest
  • Testing123guest
where did u go
Testing123guest
  • Testing123guest
sorry my computer said u left
Testing123guest
  • Testing123guest
cool one more
Mehek14
  • Mehek14
ok last question use the points (-1,5) and (1,-5) slope formula \(\dfrac{-5-5}{1-(-1)}=\dfrac{-10}{1}=-10\) so slope is -10
Mehek14
  • Mehek14
and that's it ^_^
Testing123guest
  • Testing123guest
thx man i got an 80%
