Best ResponseYou've already chosen the best response.03y = 9x + 15 3 x 0= 9x + 15 0= 9x + 15 15 15 15= 9x No what? @Jhannybean

Best ResponseYou've already chosen the best response.0But that doesn't make any sense. 15 / 9 = 1.666continued

Best ResponseYou've already chosen the best response.23y = 9x + 15 when you solved for y, you got y=5, yes? your point here became (0, 5) and when you set y to 0, you got (15/9 , 0) or (1.666... , 0) You just have to kind of eyeball the 1.66... it's a little bit past the 1.5 but no where near the 2

Best ResponseYou've already chosen the best response.2I was wrong, in stating what your points are, i would prefer writing my point as \(15/9, 0) but in graphing it, 1.6 is fine.
