Algebra / Symbolic Question

Dear All,

Here is an Algebra / Symbolic Question

Given the linear function :-

f(t):- 1/(2.75 + v1) * (t) + 1

of the form Y = M * X + B

If v1 above equals = 0.25

And the time is 12*t :-

So that gives => 1/(2.75 + 0.25) * (12 * t ) + 1

That gives Y = 5

QUESTION:- Is it possible, (and I don’t think it is), to re-write the above function f(t)

so that the ‘B’ above is symbolically replaced with only M and X?

Please advise if this is possible & show symbolical result.

Many thanks for you help attention.

Best regards,

Lea…

The "form" Y = M*X + B is a generic straight line, M is slope and B is the value of Y when X=0, the "x intercept".

Replacing "X" with "t" does not change the character of the equation. There's only so much you can do.

Many thanks for your help & attention,

Hi Fred,

Many thanks for your help & attention to my question.

The answer in your attachment - "straight lines.xmcd" is very good & almost answers my question.

Although I was wondering if it was possible to remove the Y from the right hand side of the equation because I do know the value of M & X in this example.

Best regards,
