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.
