I know there are some number crunchers out there.

A cut and paste should do it for you. Have fun!

what's m?

F(x) = (m+4)x

[RightWhale]

What are you solving for? The slope? F?

[LibWhacker]

F(x) = mx + 4x or
y=(4+m)x . . . It's a straight line through the origin with slope 4+m

[Frohickey]

f(x)=mx + 4x... um.. I think there is something wrong with how that is written. Since m is a constant, you can rewrite the function as f(x) = (m+4)x, and since m is an arbitrary constant, it could very well be f(x) = mx.

[LOC1]

You have a single equation with two unknowns, m and x. It takes two equationa to solve this. Conventionally, m would be defined in the second equation as a constant. For example, the second equarion could be m=1.

Then your original equation would be simplified to y=(1+4)x or y=5x. That plots as a straight lice through the origin with a slope of 5.
