Question

Is the m in mx+b=y the growth

Answer 1

The "m" in y = mx + b is the slope.

It is the number of units a point goes up, down, left, or right each time. Making the line linear/straight.

$m = \frac{rise}{run}$

"rise" is the the number of units you go up(+) or down(-), "run" is the number of units you go to the right

For example, if your slope is:

$\frac{1}{2}$

You are going up 1 unit, and to the right 2 units

3 or $\frac{3}{1}$

You are going up 3 units, and to the right 1 unit

$-\frac{1}{2}$

You are going down one unit, and to the right 2 units

-3 or $-\frac{3}{1}$

You are going down 3 units, and to the right 1 unit

Answer 2

well kind of, it is the slope which means the rate at which something grows or how fast it is
