Which of the statements below are true for linear functions? select all that apply.
i found that the answer is
-the general equation is y=mx+b
and -the slopeof the graph is constant and can be defined as rise over run

Hi!
I can only confirm your question:

the general equation of a linear function is y=mx+b.
More often, people however write y=ax+b

a here is the coefficient - it determines the slope and b is the constant term and it  determines the distance from the x axis

The function is graphed as a straight line, which is another way of saying that "the slope of the graph is constant"
The is another way to calculate the slope!

Ithink if im not mistaking b is -3 but im not a 100% sude
