Answer 1

The person doing the most jumping jacks per minute is Kimberly, as she completes more jumping jacks in each given period of time compared to Katrina.

The person showing a proportional relationship between time and jumping jacks is Katrina, as the number of jumping jacks she completes increases proportionally as the time increases.

The person that did the most jumping jacks initially before the time started cannot be determined based on the given information.

Therefore, the answer is neither Kimberly nor Katrina.

Answer 2

12. Suppose that the water level of a river is 34 feet after 3 days of rain and 62 feet after 10 days of rain.

Given the two points we know: (3, 34) and (10, 62) what would the point-slope equation look like?

(1 point)

(y - 10) = 4(x + 62)

(y - 3) = 4(x - 34)

(y - 34) = 4(x - 3)

(y - 34) = 4(x - 10)

Answer 3

To find the point-slope equation using the given points (3, 34) and (10, 62), we need to find the slope (m) first. Slope is determined by the change in y divided by the change in x.

m = (y2 - y1) / (x2 - x1)

m = (62 - 34) / (10 - 3)

m = 28 / 7

m = 4

Now we can use the slope (4) and one of the points (3, 34) to form the point-slope equation.

(y - y1) = m(x - x1)

(y - 34) = 4(x - 3)

Therefore, the correct point-slope equation is (y - 34) = 4(x - 3).
