Cans of Beans

On a coordinate plane, the x-axis is labeled number of cans and the y-axis is labeled total weight (in pounds. A line goes through points (5, 4) and (15, 12).

Step-by-step explanation:

Weight is proportional to the no. of cans

Let x be the no. of cans, and y be the weight

y = kx

2.4 = 3k

k = 0.8

y = 0.8x

Answer 2

Answer:

y = 0.8 x

Cans of Beans

On a coordinate plane, the x-axis is labeled number of cans and the y-axis is labeled total weight (in pounds. A line goes through points (5, 4) and (15, 12).

Step-by-step explanation:

We have 3 cans of beans weighing 2.4 lbs

Each weighs the same

2.4/3 = .8 lbs

y = .8x

4 cans = 3.2lbs

5 cans = 4 lbs

15 cans = 12 lbs

20 cans 16 lbs

Cans of Beans

On a coordinate plane, the x-axis is labeled number of cans and the y-axis is labeled total weight (in pounds. A line goes through points (5, 4) and (15, 12).

slope = ( 12-4)/(15-5) = 8/10 = .8   correct

On a coordinate plane, the x-axis is labeled number of cans and the y-axis is labeled total weight (in pounds. A line goes through points (3, 4) and (6, 8).

slope = ( 8-4)/(6-3) = 4/3 = 1.33   wrong
