4. Math on the spot An arcade deducts \( 1 / 2 \) points from a s0-point game card for each game played. The linear equation \( y=-1 / 2 x+50 \) represents the number of points \( y \) on a card after \( x \) games played. Graph the equation using the slope and \( y \)-intercept.

Solve \( x^{2}+5=17 \) using square roots. Round your solutions to the nearest hundredth
