Answer:
y= -3x
Step-by-step explanation:
The graph of a line with a proportional relationship would have the line go through the origin.
Since the 'y=-3x' equation only shows the slope of the line, it goes through (0,0), or the origin, as it's y-intercept.
y= -3x should be the correct answer.
Hope this helps.

You can use the sponge 22 times to create the design
Step-by-step explanation:
Area of the parallelogram-shaped sponge = base × height = 3 inches × 1 inch = 3 square inches
Area of design = 66 square inches
Number of times to use the sponge to create the design = Area of design ÷ Area of parallelogram-shaped sponge = 66 square inches ÷ 3 square inches = 22
The sponge can be used 22 times to create the design
If what you mean by the "percent of people 50 years old belong to group A" is the percentage of 50-year old people with respect to the total number of people belonging to group A, then the answer is
32/(19+32) * 100 = 63%
But, if what you mean is the percentage of 50-year old people in group A with respect to the total number of 50-year old people, then the answer will be
32/(32+24) * 100 = 57%
