Algebra 2 Writing Linear Functions
Lecture Description
In this lecture, we'll see two ways of writing linear functions which will help us solve linear equations and problems involving parallel and perpendicular lines. The first way is the slope intercept form, y=mx + b, where m is the slope, and b is the y-intercept. This is useful when we need to graph a line. In the example, you'll see exactly how the slope intercept form will help you graph the function. The second way is the point slope form which includes a point on the line and the slope of the line and is related to the slope formula.

Why do you at 12:15 minute in order to isolate B, you substrated 4/3 from both sides, is that right? i was taught that when you working with fraction (to pass it to the other side of the equation) you should do it by its reciprocal which would be -3/4. WOULD YOU PLEASE HELP ME to clear thing out. THANKS!!!

i am a bit confused about the difference of the y value and the y intercept, why one can not plug in the y value on b

Do we approach the problem the same way if the slope is a fraction while using the point slope method.
