Families

Lines: y=mx + b -when the slope is the same+= series f parallel lines y=-2x+b<--- parameter -when y-intercept is the same y=mx+3 M is the parameter or x=0

Parabola: y=a(x-h)^2 + k -when "h" is constant, "a" is constant, "k" changes--> Parabola's vertex moves uo and down -when "a" is constant, "k" is constant, "h" changes--> Shape doesn't change -when "h" is constant, "k" is constant, "a" changes--> Width and direction of opening change

Function: Have one parameter and one constant value
