Respuesta :
For this case, what we are going to do is write a linear equation of the form:
 T = 7.5 * x -10
 Where.
 7.5: heating speed of the pizza.
 -10: initial temperature.
 x: time in minutes.
 For x = 12 we have:
 T = 7.5 * (12) -10
 T = 90-10
 T = 80
 Therefore the equation is correct.
 Answer:
 T = 7.5 * x -10
 See attached image.
