Can someone please give an example on how to solve a y=mx+b problem

2. With regards to what?
With regards to m:
$
y = mx + b
$

$
m = -\frac{b}{x}
$

With regards to x:
$
y = mx + b
$

$
x = -\frac{b}{m}
$

With regards to b:
$
y = mx + b
$

$
b = -mx
$

Was that what you meant? If you meant something else, you have to specify... Pretty standard algebra...

3. Can someone please give an example on how to solve a y=mx+b problem?

What is the equation of a line with slope 2 through point (4.6)?
y = mx+b Plug in the slope instead of m along with the x and y values of the point -->
6 = 2(4) +b Solve for b -->
6 = 8 +b
b = -2

Re-write the format, including the values of m and b -->
y = 2x -2
