the slope of a line is y2 -y1 / x2 -x1 i will pick x1 = 0 and x2 = 2 The slope becomes -2 - (-2) / 2-0 = 0/2= 0 zero slope which is answer d.

|dw:1443791275677:dw| an undefined slope looks like this
dakid88
  • dakid88
no it dont firekate

  • anonymous
Its zero Slpoe I promise!!!

its zero, I'm not too sure how I can explain this properly, but for horizontal lines, the slope is always zero

Dude just stop your only saying D so you can get the stupid medal but at this point idc about it I just want him to get the right answer!

formula to find slope \[\huge\rm \frac{ y_2-y_1}{ x_2-x_1 }\] since the line is horizontal |dw:1443791506934:dw| horizontal line when y is constant and x values are changing
dakid88
  • dakid88
u dont tell me wht to do redneckk and me too
Nnesha
  • Nnesha
let's say we have (2,3)(4, 3)( notice y values are the same ) plugin \[\frac{ 3-3 }{ 4-2 }\] when you subtract same numbers what would you get in this question 3-3 =?
Nnesha
  • Nnesha
remember the formula is = change in y's over change in x's
anonymous
  • anonymous
ok so im going with zero slope thank you everyone i'll tell you who's right a bit later and medal them
Nnesha
  • Nnesha
did you understand ???
anonymous
  • anonymous
yeah a bit that helps with the rest of the questions i might have thank you
Nnesha
  • Nnesha
alright just practice remember when we subtract same numbers we will get zero so zero divided by anything would be just 0
anonymous
  • anonymous
ok got it :)
Nnesha
  • Nnesha
let's say if we have vertical line |dw:1443791845577:dw| in this questions x value would stay the same
Nnesha
  • Nnesha
so when substitute points into the formula (3,2)(3,4) (x values would be the same ) \[\frac{ 4-2 }{ 3-3 }= ???\]
Nnesha
  • Nnesha
i'm pretty sure ur next question would be on vertical line slope
anonymous
  • anonymous
yeah it is
Nnesha
  • Nnesha
alright so \(\color{blue}{\text{Originally Posted by}}\) @Nnesha so when substitute points into the formula (3,2)(3,4) (x values would be the same ) \[\frac{ 4-2 }{ 3-3 }= ???\] \(\color{blue}{\text{End of Quote}}\) solve this
anonymous
  • anonymous
2/0
Nnesha
  • Nnesha
i just picked two points but for vertical line x -coordinate would be the same 4sure
Nnesha
  • Nnesha
right so answer would be what 2/0 = ?
anonymous
  • anonymous
0 so zero slope?
Nnesha
  • Nnesha
no no you can't divide by zero whenever u get `0 at the denominator ` answer would be undefined bec you can't divide by 0
anonymous
  • anonymous
oh undefined ok bc thats what i originally thought
dakid88
  • dakid88
i told u
anonymous
  • anonymous
i knew there was some rule between the horizontal or vertical slope i just forgot which
anonymous
  • anonymous
@dakid88 we're on a different question so actually, you're wrong
dakid88
  • dakid88
oh my bad
anonymous
  • anonymous
its all right i understand it now
