The points (-11, r) and (-6, 12) lie on a line with slope 2. Find the missing coordinater r.

r=2

Step-by-step explanation:

We can use the given 2 points to find slope. Since we are given the slope, we can plug it into the formula and solve for r.

                                       [plug in values]

                                  [combine like terms]

                                         [multiply both sides by 5]

                                     [subtract both sides by 12]

                                         [divide both sides by -1]

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

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.
