Pl help m i do anything just help

1.) Create a table of x and y values that represents a proportional relationship.

a) Explain how you know the relationship is proportional.

b) What equation models the values in the table?

2) Create a table of x and y values that represents a linear, non-proportional relationship.

a) Explain how you know the relationship is non-proportional.

b) What equation models the values in the table?

Table could be first x = 2, y = 4, then x = 4, y = 8. It is proportional because both (x,y) values equal 1/2. The equation is x = 1/2y. Last, the table could be the same, or you could do first, x = 6, y = 12, then x = 12, y = 24, because they still equal 1/2.

Step-by-step explanation:

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
