EXAMPLE: Soria inherited his dad’s baseball card collection has been collecting baseball cards since he was five years old. He knows that every year he has been given 4 baseball cards from his grandpa, a birthday tradition they have had. At 10 years old, he decided to count how many cards he has and found that he has 32 cards! What does the y-intercept represent in this situation? How many did Soria inherited from his dad? How do you know? Show thw work. Write an equation for this situation. Use your equation to solve how many cards Soria has at 35 years. Show all your work below. Though sometimes it may be feasible to work backwards to find the term, it is not always “b” possible. EXAMPLE: Find the equation of a line that goes through (50, 26) and has has a slope of -2. Show all the work below. Steps Example : Find the equation of a line that goes through (14, -4) and has a slope of ½. Write y = mx + b Plug in the information you know. Solve for “b”. Write the equation. NOW YOU TRY
