Rewrite the statement in conditional form. lines with the same slope are parallel

If lines have the same slope, then they are parallel.

Step-by-step explanation:

The first part of the given statement sets up the condition for the second part to be true. A conditional statement makes that explicit.

(lines described by first part) are (lines described by second part) ⇒

if (lines are described by first part), then (lines are described by second part)

Your conditional statement can be written ...

If lines have the same slope, then they are parallel.
