A large school district is reevaluating it\'s teachers salaries. They have decided to use regression analysis to predict mean teachers salaries at each elementary school . The researcher uses years of experience to predict salary . The resulting equation was
Y=24266.98 + 1289.10x where y =salary and x =years of experience
Based on the equation by how much could a teacher expect his /her salary to increase for every additional year of service ?
1289.10
1289.10x
1289.10+x
24266.98
