1. The slope intercept form is y=mx+b. m=the slope and b=the y-intercept 2. You can tell if it is a function or not because the x values can never repeat if it is a function. 3. y=1m+4 because the slope is 1 and y-intercept is 4 though you would really write it as y=m+4.

The more money you invest and the earlier you start means your retirement savings will have that much more time and potential to grow and investing early you can be able to take advantage of compound earnings.
