Solve the system of linear equations by graphing.
y = –y equals negative startfraction 5 over 2 endfraction minus 7.x – 7
x + 2y = 4

High schoolmathematics 5 points keith is the leading goal scorer for a team in an ice hockey league. last season, he scored 42 goals in 82 games. assuming he scores goals at a constant rate, what is the slope of the line that represents this relationship if the number of games is along the x-axis and the number of goals is along the y-axis?

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
