The slope is 2, while the y-intercept is 4. This equation represents starting with 4 cards and adding 2 cards each week.

Step-by-step explanation:

Given the equation which describes the number of cards, y, you have after x weeks: y=2x+4

Comparing this with the slope intercept form of the equation of the line: y=mx+b, where:

m is the slopeb is the y-intercept.

We have that:

Slope

Slope, m=2.

A slope of 2 indicates that you buy 2 cards per week.

The y-intercept

The y-intercept of the line, b=4.

This is the starting value. In this case, it represents the number of cards you were given by your friend.

The slope is 2, while the y-intercept is 4. This equation represents starting with 4 cards and adding 2 cards each week.
