Answer:

  • slope: 45
  • y-intercept: 30
  • equation: y = 45x + 30

Step-by-step explanation:

The slope is the cost per month. (A slope is often expressed as a ratio: dollars per month, in this case.) The slope is 45.

The y-intercept is the value that obtains when the number of months (in this case) is zero. It is the activation fee, 30. The y-intercept is 30.

The equation in slope-intercept form is ...

  y = mx + b . . . . . where m is the slope and b is the y-intercept

Using the above numbers, the equation is ...

  y = 45x + 30
