Brian received 45 trading card from his mother and twenty-five trading cards from his uncle to start a collection. Each week Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection. write a equation in slope intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.

Respuesta :

Answer:

The representation of Brian's situation in slope intercept form is:

                               y= 15x +70

Step-by-step explanation:

Let x be the number of weeks Brian started his collection.

y be the number of cards Brian has at present.

                          y= 45+25+ 15 x

                    or, y= 15 x +70

which is in the form of,

                               y= mx +c                (slope intercept form)

where,

m= slope

x= x- intercept

c= constant.
