two lines are parallel if their slopes are the same
anonymous
  • anonymous
so how do i solve this?
anonymous
  • anonymous
equation of a line in the slope intercept form is y = mx+b. where m is the slope.

so not the first equation but the second one, i have to put it in y=mx+b right?
anonymous
  • anonymous
yes, put the second equation in the slope intercept form.
anonymous
  • anonymous
how would i do that
anonymous
  • anonymous
wait. are you sure the second equation is y - ky = 7?
anonymous
  • anonymous
noo its y-kx=7
anonymous
  • anonymous
okay. so express it in the form y = mx+b, in otherwords, isolate y on the LHS and take the x term and constant term over to the RHS

Y=KX+?
anonymous
  • anonymous
Y=KX+7?*
anonymous
  • anonymous
yes.
anonymous
  • anonymous
so the equations y = 2x-7 and y = kx+7 are parallel when their slopes are parallel. for an equation y = mx+b, m is the slope. these hints should be more than enough to help you solve this problem
anonymous
  • anonymous
sorry I meant to say they are parallel when their slopes are equal.
anonymous
  • anonymous
its okay, thankyou
