4) What is the slope of the line joining (8, 15)
and 4,5)

5/2

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(5 - 15) / (4 - 8)

-10 / -4

= 5/2

So, the slope of the line is 5/2

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.

- (2, -7)

- lines r and s and lines t and u must be parallel
