Q. What is the slope of a line that is parallel to the line \(y = x + 2\)?
Answer
In slope-intercept form \(y=mx+b\) the slope is \(m\); for \(y=x+2\) we have \(m=1\), so any line parallel to it has slope \(1\).
Final answer: \(1\).
Detailed Explanation
Problem
Find the slope of a line that is parallel to the line \(y = x + 2\).
Step-by-step explanation
-
Recognize the slope-intercept form.
Lines written as \(y = mx + b\) are in slope-intercept form, where \(m\) is the slope and \(b\) is the y-intercept. What to do: identify the equation’s form and locate the coefficient of \(x\).
-
Identify the slope of the given line.
Compare \(y = x + 2\) to \(y = mx + b\). Rewrite explicitly as \(y = 1x + 2\). What to do: read off the coefficient of \(x\); here \(m = 1\).
-
Use the property of parallel lines.
For non-vertical lines in the plane, two lines are parallel if and only if they have the same slope. What to do: take the slope of the given line and use it for any line parallel to it.
-
State the slope of any line parallel to the given line.
Therefore, the slope of a line parallel to \(y = x + 2\) is \(1\).
Answer: The slope is \(1\).
