IM 8.3.3 Practice: Representing Proportional Relationships

Here is a graph of the proportional relationship between calories and grams of fish:

Write an equation that reflects this relationship using [math]x[/math] to represent the amount of fish in grams and [math]y[/math] 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 [math]M[/math] is the amount of money the students collect for selling [math]R[/math] raffle tickets. Write an equation that reflects the relationship between [math]M[/math] and [math]R[/math].

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 [math]\frac{y}{x-2}=\frac{3}{11}[/math]. What are the coordinates of some points that lie on the line?

Graph the line.
