Best ResponseYou've already chosen the best response.0just use the replace and solve method. Replace y with 0, solve for x. : x intercept. Replace x with 0, solve for y : yintercept

Best ResponseYou've already chosen the best response.0in order to isolate x, we have to divide both sides by 2

Best ResponseYou've already chosen the best response.2agreed with Jhannybean 2x means "2 times x" so if we had 2x = 1, and we wanted to isolate x, we undo the multiplication of the 2 the opposite of multiplication is division. You must divide both sides by 2 to isolate x

Best ResponseYou've already chosen the best response.0You first have to divide 2x by both sides so you would end up with y= x + 2

Best ResponseYou've already chosen the best response.2I think you meant `x = 0.5` ?

Best ResponseYou've already chosen the best response.2correct. That or x = 1/2 which is the same thing in different form

Best ResponseYou've already chosen the best response.2@Jhannybean why do that? You stated above that y = 0. That's what led to x = 0.5 Don't you mean plug in x = 0 ?
