Step-by-step explanation: Typcally we use different forms once it is given different information and we need to calculate something.
Slope intercept form: Normally we use this form whenwe know a specific point that is the y-intercept.
Point intercept form: Used when we have the slope of the function and also a given point (not the y-intercept)
Standard: Used generally for algebric calculations
Final answer: All the information above are important but at the end all the forms represent the same function so we can use all of then to be able to work with our function as to write a graph or other things all depends on what information is given to use about our function
