The coefficient is the change in y for each increase of 1 in x.
Optional until a teacher marks it
In y = 4x + 2, what happens when x increases by 1?
The coefficient is the rate of change. The constant shifts every value but does not change how much y grows from one x to the next.
Problem 1 of 8. What we learned, an example, a few together, then independent practice.
