The equation of a line in slope intercept form is y=mx + b where m is the x intercept

This question does not really make sense.

How ever I’ll try to respond to this with the best of my ability.

y=mx+b is nothing but slope intercept form.

M is slope value. B is the y-intercept.

There is really no need for x-intercepts in slope intercept form.

Hope this helps. :)

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
