Write a linear equation in slope intercept form to model the situation: A telephone company charges $28.75 per month plus 10 cents a minute for long distance calls.

y=1/10C-23/8x

Step-by-step explanation:

Linear Equation:

Ax+By=C

Slope Intercept Form:

y=mx+b

So, the linear equation is the following;

28.75x+10y=C

Now, to change it into slope intercept form you must get 'y' alone;

28.75x+10y=C

-28.75x         -28.75x            

10y=C-28.75x                        

10y/10=C/10-28.75x/10

y=1/10C-23/8x

3x + 4y -25 =0 represents the amount of change sianna should recieve
