Question 301416: How would I graph c=30t+20? and also Media services charge $20 for a phone and $30/month for the economy plan, the equation c=30t+20 describes the total cost, c, of operating a media services phone for t months.what is total cost for 3 months of service? and also if a customer has $90 how many months of services can they get? Thanks so much

You can put this solution on YOUR website!
Plot c on the vertical axis, and t on
the horizontal axis
You plot it by plugging values of t into the equation
and finding c, like
t+=+1
c+=+50
Here's the plot:
+graph%28+400%2C+400%2C+-2%2C+6%2C+-5%2C+120%2C+30x+%2B+20%29+
