Best ResponseYou've already chosen the best response.0u should know the 2 points through which your line is going or one x or y coordinate can be not given, but then you have to know the slope to solve for this coordinate

Best ResponseYou've already chosen the best response.0if the yintercept is 12 and the xintercept is 5 ... how do i know which one to plug in where?

Best ResponseYou've already chosen the best response.2y = mx + b where m is slope and b is yintercept xintercept is when y =0 so you can write it in parentheses (x,y)>>(5,0)

Best ResponseYou've already chosen the best response.0no but in the y2y1/x2/x1

Best ResponseYou've already chosen the best response.2ohh so if yintercept is 12 remember yintercept when line cross yaxis when x=0 so (0 ,12) and xintercept like i say x when line cross xaxis when y = 0 so (5,0)

Best ResponseYou've already chosen the best response.0yea so how do i know which goes first in the y2y1/x2x1

Best ResponseYou've already chosen the best response.2dw:1433802336037:dw and it doesn't matter just remember y values should be at the top

Best ResponseYou've already chosen the best response.0so it doesn't mater if the 12 is y2 or y1 in the equation? and the same for the 5 ?

Best ResponseYou've already chosen the best response.0i'm supposed to get a 12/5 but if i plug it in anywhere i can also get a positive 12/5

Best ResponseYou've already chosen the best response.2or you can see which number is coming first for exxample (5,0)(0,12)dw:1433802577923:dw (0,12) is first so y_1 is 12 that's how i do it

Best ResponseYou've already chosen the best response.0so left to right whatever is first? so it would be 120/ 05?

Best ResponseYou've already chosen the best response.2\(\color{blue}{\text{Originally Posted by}}\) @yomamabf i'm supposed to get a 12/5 but if i plug it in anywhere i can also get a positive 12/5 \(\color{blue}{\text{End of Quote}}\) (5,0)(0,12) \[\huge\rm \frac{ 120 }{ 05 }=\frac{ 12 }{ 5 }\] now other way (0,12)(5,0) \[\frac{ 012 }{ 50} = \frac{ 12 }{ 5 }\] same ?

Best ResponseYou've already chosen the best response.0also it can be this too right? y=m(5)+12 =12/5

Best ResponseYou've already chosen the best response.2nope x_2  x_1 = 5 in this case bec x = 0 so that will work but NO!

Best ResponseYou've already chosen the best response.2Let x_2 = 3 and x_1 = 1 x_2  x_1 = 21 =1 so you CAN'T substitute 1 for just x

Best ResponseYou've already chosen the best response.2but you can pick any x value from two order pair (5,0)(0,12) to plug in this equation y = mx+b u will get the same answer
