What are the key features for a linear function, and how can you use those features to sketch graphs? explain them through examples

In a linear function, you are given a function labeled as y=mx+b. The key features to look for are the slope and the y-intercept. The slope is represented by m, while the y-intercept is represented by b. For example, in y=3x+7, 3 is the slope while 7 is the y-intercept.
