What is the slope intercept form for x+3y=0
Norma-Jean [14]

Answer:

y = -1/3 x

Step-by-step explanation:

what is the slope intercept form for x+3y=0

Slope intercept form solves for y:

x + 3y = 0

subtract x from both sides:

x + 3y - x = 0 - x

3y = -x

divide both sides by 3:

3y/3 = -x/3

y = -1/3 x

What positive whole number can you multiply by 3 and add1,or multiply by 2 and add 8?
Vilka [71]

Answer:

7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.

Step-by-step explanation:

Multiplying the positive whole number 7 by 3 and adding 1 will get:

(7 × 3) + 1 = 21 + 1 = 22

Multiplying the positive whole number 7 by 2 and adding 8 will get:

(7 × 2) + 8 = 14 + 8 = 22

Therefore, 7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.
