  We have:
  The generic equation of the line is:  y-yo = m (x-xo)
  The slope is:
  m = (y2-y1) / (x2-x1)
  m = (- 2-0) / (3-0)
  m = -2 / 3
  We choose an ordered pair
  (xo, yo) = (0, 0)
  Substituting values:
  y-0 = (- 2/3) (x-0)
  Rewriting:
  y = (- 2/3) x
  Answer:
  The equation of the line is:
  y = (- 2/3) x

What is the value of y in the equation 3(3y − 15) = 0? 5 6 7 9
mezya [45]
Y = 5
3(3y - 15) is also equal to 9y - 45, which means to find y, you have to divide 45 by 9, which is 5.

Find the slope-intercept form of the equation of the line passing through the given points.
Ugo [173]
The\ slope-intercept\ form:y=mx+b\\\\The\ slope-point\ form:y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

(1;\ 1)\to x_1=1;\ y_1=1\\\left(3;-\dfrac{1}{5}\right)\to x_2=3;\ y_2=-\dfrac{1}{5}.\\\\Subtitute:\\\\m=\dfrac{-\frac{1}{5}-1}{3-1}=\dfrac{-1\frac{1}{5}}{2}=-\dfrac{\frac{6}{5}}{2}=-\dfrac{\not6^3}{5}\cdot\dfrac{1}{\not2_1}=-\dfrac{3}{5}


y-1=-\dfrac{3}{5}\left(x-1\right)\\\\y-1=-\dfrac{3}{5}x+\dfrac{3}{5}\ \ \ \ |add\ 1\ to\ both\ sides\\\\\boxed{y=-\frac{3}{5}x+1\frac{3}{5}}

What is the answer??
Lubov Fominskaja [6]

Answer:

<h2>(0, -2)</h2>

Step-by-step explanation:

A(x, y)

rotated 180°: A'(-x, -y)

translated n units:

left (x - n, y)

right (x + n, y)

up (x, y + n)

down (x, y - n)

We have R(-3, 2)

rotated 180°: (-(-3), -2) = (3, -2)

translated 3 units left: (3 - 3, -2) = (0, -2)
