What is the slope of a line PARALLEL to the graph?
es
A)-3
B)0
C)3
D)-1/3

As a rule, parallel lines will always have the same slope.

The || symbol represents "parallel".

So if the slope of a line is parallel to this graph, the line

must have a slope of 3 since this line has a slope of 3.

As a quick review, remember that slope describes how steep a line is.

It can be found using the ratio rise/run between

any two points that are on that line.
