Best ResponseYou've already chosen the best response.0Well you can begin by recalling that you can obtain the x intercept, by setting y to be zero and solving for x. Likewise you can get the y intercept by setting x to be zero and solving for y

Best ResponseYou've already chosen the best response.1intercepts are fun if; I do it like this: given a linear equation: ax + by = c, we can divide out the c \[\frac{ax}{c}+\frac{by}{c}=\frac{c}{c}\]then we can divide off the numerators as well:\[\frac{x}{c/a}+\frac{y}{c/b}=1\] and your intercepts are just the denominators now

Best ResponseYou've already chosen the best response.12x4y=16 2x/16 4y/16 = 16/16 x/16/2 + y/16/4 = 1 x/8 + y/4 = 1 you xint = 8 and your yint = 4

Best ResponseYou've already chosen the best response.13y + 6x = (18) 3y/(18) + 6x/(18) = (18)/(18) y/18/3 + x/18/6 = 1 y/6 + x/3 = 1 xint=3, yint=6
