rudy can make 7 holiday cards with the cardstock he already has on hand. he is also buying more paper, and he can make 10 additional cards with each package of cardstock he buys. write an equation that shows how the total number of cards rudy can make, y, depends on the number of packages of cardstock he buys, x. y =

rudy can make 7 holiday cards with the cardstock he already has on hand. he is also buying more paper, and he can make 10 additional cards with each package of cardstock he buys. write an equation that shows how the total number of cards rudy can make, y, depends on the number of packages of cardstock he buys, x. y =

Answer

Explanation:

Step1: Identify the initial value

Rudy already has 7 cards. This is the y - intercept (b) in the linear equation (y = mx + b).

Step2: Identify the rate of change

Each package gives 10 additional cards. So the slope (m = 10).

Step3: Write the linear equation

Using the slope - intercept form (y=mx + b), substitute (m = 10) and (b = 7).

Answer:

(y = 10x+7)
