Choose the graph below that correctly represents the equation 3x + 9y = -18.
3x + 9y = -18
9y= -3x -18
y= -1/3x - 2

The graph in the attached figure

Step-by-step explanation:

we have

Isolate the variable y

Divide by both sides

The slope of the line is negative  

The y-intercept is equal to the point (value of y when the value of x is equal to zero)

The x-intercept is equal to the point (value of x when the value of y is equal to zero)

Plot the intercepts to graph the line

see the attached figure

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
