# How do you graph #x-y=1 #?

##### 2 Answers

Determine the x- and y-intercepts, plot them, and draw a straight line through the point.

#### Explanation:

Graph:

**X-intercept: value of #x# when #y=0#**

Substitute

x-0=1#

**The x-intercept is #(1,0)#. Plot this point.**

**Y-intercept: value of #y# when #x=0#**

Substitute

Multiply both sides by

**The y-intercept is #(0,-1)#. Plot this point.**

Draw a straight line through the points.

Please read the explanation.

#### Explanation:

We are given the equation:

**How do we graph this linear equation ?**

We have

The given equation can be reduced to a more simpler form.

Subtract

Multiply both sides of the equation by

Now, we have the equation in **Slope-Intercept Form**:

**Slope** and

**y-intercept**.

Hence,

**Slope :**

**y-intercept :**

The **x-intercept** is where the graph crosses the **x-axis**

Set **x-intercept**:

Add

Hence **x-intercept**.

Plot the points **x-intercept** and **intercept** on the graph.

Join the two points to get the straight line.

**This is the graph of the linear equation.**
