Asap 15 points 1) (multiple answers pick two) does the equation represent a direct variation? if so, identify the constant of variation. 17y = 85x a) yes b) no c) 5 d) 1/5 2) determine whether the relationship is a direct variation. x : 3, -1 , -4 y : -6, 2, 8 a) yes b) no 3) is the relationship shown a direct variation? (it's not absolute value is a table chart) | x  | y | | -2 | 5  | | 1  | 3  | | 4  | 1  | a) yes b) no 4) determine whether the relationship is a direct variation. | x |    6    |    9    |    17  | | y | 13.2 | 19.8 | 37.4 | a) yes b) no 5) determine which equation does not represent a direct variation. a) 6x - y = 0 b) y = 4x + 1 c) y = -2x d) y = 1/3x 6) (multiple answer pick 2) tell whether the equation represents a direct variation. if so identify the constant of variation. y + 3x = 0 a) yes b) no c) -3 d) 1/3 e) 3

1.) The answer is (B) No, because direct variation is written as y = kx, but the problem was not written that way.

2.) Yes; if you write x = ky, you will find that each x value given multiplied by a common k equals a corresponding y value.

3.) No; each x value does not multiply by a constant k to get the y values.

4.) Yes; each x value multiplies by 2.2 to get each corresponding y value.

5.) B; this is the only one that isn't or can't be written in y = kx form.

6.) Yes & -3; y + 3x = 0 can be written as y = -3x, which is a direct variation equation. The constant is just the -3.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
