Create a real life scenario in which you show how you interpret key features of functions and graphs such as slope and y-intercept?

The y intercept is the point on the graph when your x value is zero. so starting out I have 300 dollars to begin with. that would be my y intercept. my slope is my rate of change in y/x. I know that each month my account is growing by 12 dollars so:y=12x+300

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
