on your math quiz you earn five points for each question that you answer correctly in the table below X represents the number of questions that you answer correctly and Y represents the total number of points you score on your quiz fair enough the relationship between these two variables can be expressed by the following equation y is equal to 5x graph the equation below so you could look at a couple of your points you could say well look if I got 0 questions right I'm going to have 0 points so you could literally graph that point if I got 0 questions right I get 0 points and then if I get one question right the table tells us that or we could logically think about it every question I get right I'm going to get 5 more points so if I get one question right I'm going to get 5 more points and we saw that in our table as well we saw that right over here 1 question 5 points we could also plot it 2 questions 10 points any of these but you only only have to do two points to define a line so it looks like we are actually done here
