1. the linear equation y = 3x tells us that this line is going to be more vertical or horizontal? explain.

More vertical. 
y=x, where the slope is 1, is a line that forms a 45 degree angle with the positive part of the x axis. y=3x has a bigger slope, so it is going to rise 3 times faster than y=x so the line is more vertical
I hope that makes sense.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is 18.

She should use 12/3 to measure
