True. Using the equation y2-y1 / x2-x1
The new equation should look like this 5/1-3/1 and the equals to = 4/2 and that simplify is 2. So the answer 2 we just got is the slope. So we just add the letter x since that represents slope. Making the equation y=2x+1 true.
So, firstly, in order for us to know how much is each baseball card pack, we divide 12 dollars by 4 and we get 3. Therefore, each baseball card pack costs $3. So for 21 dollars, he can purchase 7 baseball card packs. 21 divided by 3 is 7. Hope this answers your question. Have a great day!
