Which table shows a proportional relationship between x and y? a 0,4 1,8 2,12 b 0,0 1,1 2,4 c 1,4 2,8 3,12 d 1,2 2,4 3,8

The correct option is C.

Step-by-step explanation:

The proportional relationship between x and y is defined as

Where, k is constant of proportion.

In option A, the rate of change is constant because the value of y increased by 4 as the value of x increased by 1.

If a line passing through two points, then the equation of line is

The equation of a line

It is not in the form of . So, option A is incorrect.

In option B, the rate of change is not constant because the value of y is not increasing by a constant rate the value of x increasing by 1. So, option B is incorrect.

In option C, the rate of change is constant because the value of y increased by 4 as the value of x increased by 1.

The equation of a line

It is in the form of . So, option C is correct.

In option D, the rate of change is not constant because the value of y is not increasing by a constant rate the value of x increasing by 1. So, option D is incorrect.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
