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

12/100 = x/350
x = 12*350/100
x = 42 liters

Question 2

1 basket → 5 1/2 kg ⇒ 2 baskets → 2(5 1/2) = 11 kg
1 kg → 30 ⇒ 11 kg → 11*30 = 330

PLEASE HELP!!!!!!!! IMAGE ATTACHED!!!!

Answer:

Step-by-step explanation:

4) (-2,3) ; (-1,-2)

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-2-3}{-1-[-2]}\\\\=\frac{-5}{-1+2}\\\\=\frac{-5}{1}\\\\=-5$

5) line is parallel to x-axis. So, slope= 0

6) (1,1) ; (-2, -1)

$Slope=\frac{-1-1}{-2-1}\\\\=\frac{-2}{-3}\\\\=\frac{2}{3}$
