You are hiding the rest of the given information.
m, x, b, are variables. That's is all you have indicated. Where is your variable, "t"?

Now maybe you have something like y=mt+b.
Still incomplete description.


Give the complete problem description, word for word.

FURTHER THOUGHT-------------------------

Here is just a guess at the actual formula you might have been given:
y=(1/7)t+75.5
or
y=t%2F7%2B75.5

If THAT is actually the formula given in YOUR actual problem description, then 1%2F7 is the slope, the way the life expectancy changes with time; and 75.5 would be the life expectancy IN 1970, which was taken as t=0.
