*Review from last class*

Your Turn! { (x,y) | 4x- y ≥ 3 , xεR, yεR} Graph the solution of the inequality { (x,y) | 4x- y ≥ 3 , xεR, yεR}

We can also apply this idea to word problems!

What inequality represents the goal? let x = number of pairs of skis let y = number of snowboards 100x +120y > 600 Are there any restrictions? Since half a snow board, or a third of a pair of skis cannot be sold, the 

solution set is discrete. xεW, yεW

inequality xεW, yεW restrictions 100x +120y > 600 10x + 12y = 60 x intercept 10x = 60 x = 6 (6, 0) y intercept 12y = 60 y = 5 (0, 5) {(x,y) Ι 100x + 120y > 600, xεW, yεW}
