Question

Which equation has a graph parallel to the graph of 9x + 3y = –22

Answer 1

Are there choices?

Answer 2

Parallel lines have the same slope.
You need to find the slope of the given line and the slopes of all the choices.
The choice that has the same slope as the given line is the answer.
To find the slope of a line, solve the equation of the line for y, and write it in the form
y = mx + b
Then m is the slope.
