notes: Graphing Linear Equations in Slope-Intercept Form september 13, 2016 Warm-Up: x-and y-intercepts 42 You have $16 to spend at the carnival. Ride tickets cost $4 each and game tickets cos t¥ each. The equation, 4x +2y =16 models the situation, where x is the number of ride tickets purchased and y is the number of game tickets purchased. aioe Find the x- and y-intercepts and graph the equation. Then interpret the graph in the context of the situation and find four possible solutions. é intercept: nyt 2 doy =e —- no) e ee ef b&b G= Uy (x = 0) ee Cagis Nymber yon lercept 2 loo Ondes, Beers purchoseh.
