Here is a graph of the proportional relationship between calories and grams of fish:
Write an equation that reflects this relationship using to represent the amount of fish in grams and to represent the number of calories.
Use your equation to complete the table:
Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell.
Suppose is the amount of money the students collect for selling raffle tickets. Write an equation that reflects the relationship between and .
Label and scale the axes and graph this situation with M on the vertical axis and R on the horizontal axis. Make sure the scale is large enough to see how much they would raise if they sell 1000 tickets.
Describe how you can tell whether a line’s slope is greater than 1, equal to 1, or less than 1.
A line is represented by the equation . What are the coordinates of some points that lie on the line?
