Acell phone package charges $39 even if 0 minutes are used during the month. each additional minute of talk time adds a $0.07.write an equation to model this situation in slope-intercept form.

Total monthly cost (x) = $39 + ($0.07/min)x

Step-by-step explanation:

The y-intercept is $39.  The slope is ($0.07/minute)x, where x is the number of talk minutes.  Thus:

Total monthly cost (x) = $39 + ($0.07/min)x, where x is the number of talk minutes.
