Best ResponseYou've already chosen the best response.0Get Y free to on side.. And then you find the slope.. Use it for build a Equation of the given point..

Best ResponseYou've already chosen the best response.0\[2x5y=7\] \[y=(2x7)\div5\] \[y=2x \div57\div5\] And the slope is then 2\5.. k=2.5 , and x =4 , y =9 Use it : Y=kx+m

Best ResponseYou've already chosen the best response.0slope can be remembered as a/b which in this equations is: 2/5 = 2/5

Best ResponseYou've already chosen the best response.0the short cut to a parallel line equation is to just plug in your values of (x,y) = get the "new" answer, for example: 2x5y=7 ; (x=4,y=9) 2(4) 5(9) = ? 8 +45 = 53 "new" equation for PARALLEL line is: 2x 5y = 53 ;(4,9)

Best ResponseYou've already chosen the best response.0ahh. even shorter way thx... iam Used to work with y=kx+m .

Best ResponseYou've already chosen the best response.0i used the y=mx+b as well, but after so many times, I noticed this pattern :)
