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.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
