On Your Own 4. (MP) Model with Mathematics Reanna is making a scrapbook which holds 14 photos on each 2-page spread. Make a table of values to represent this relationship. Write an equation for the situation. 2-page spreads, x Photos, y Tell whether each table represents a proportional relationship. If it does, identify the constant of proportionality. 5 X 3 7 9 X 14 15 16 63 147 189 21 22.5 15 7. Determine whether the table represents a proportional relationship. If it does, find the constant of proportionality and use it to write an equation to represent the table of values. X 2 3 4 5 14 21 28 35 B. The equation y = 8x gives the number of slices y in x pizzas. Make a table of values using the equation. Identify the constant of proportionality. Then complete each sentence.
