1.) johnny and alex went on a fishing trip and caught 31 fish. johnny caught one less than
three times as many fish as alex caught. write an equation to figure out how many fish each
boy caught

4x = 32. Where x = number Alex  and 3x - 1 is the number caught by Johnny.

Step-by-step explanation:

Let the number of fish that Alex caught be x.

Then the number of fish Johnny caught is

3x - 1.

So 3x - 1 + x = 31

4x = 32.

A. -1.8

Step-by-step explanation:

If x is the independent variable and y is the dependent variable, therefore constant of proportionality would be:

k = y/x

Using any pair of values from the table, we can find k. Let's use (3, -5.4):

k = y/x = -5.4/3

k = -1.8
