7th ACA Test 3-2 Review: Linear Relationships

Diego is in the defense on the football team. In 1 game he intercepted the football 18 times. Write an equation that best represents y, the total number of footballs Diego intercepts in x days if he continues at this rate?

• y = 18x

• y = x + 18

• y = 18 + x

• y = x/18
