Answer:

0.07

dollar per minute

Step-by-step explanation:

Given the charging formula :

C(n) = 13 +0.07n

n = number of minutes talked, and

C(n) = monthly charge, in dollars

The slope is the change in amount charged per change in the number of minutes talked.

Also, from The slope intercept equation :

y = mx + c

Comparing the equation :

0.07n = mx

m = 0.07

Since, The slope is the change in amount charged per change in the number of minutes talked.

Amount charged in dollars, talk time measured in minutes ;

Unit = dollar per minute

Write the equation in point slope intercept form of the line that passes through (6,-11) and is parallel to the graph of y=-2/3x
Alina [70]

Answer:

y+11=-2/3(x-6)

Step-by-step explanation:

To find the parallel line, we would just plug in the numbers in the point-slope form from what we're given. We have y=-2/3x+12 and (6,-11).

Point-slope form:

y-y1=m(x-x1) → y+11=-2/3(x-6)

m represents the slope, which is -2/3 in this situation.

y1 represents the y coordinate, which is -11 in this situation. However, when we plug in negative numbers in a point-slope form, we would do the opposite of the negative number, which is to make it a positive in point-slope form.

x1 represents the x coordinate, which is 6 in this situation.
