# How do you graph #x - y = 10#?

##### 2 Answers

you just have to insert numbers for

#### Explanation:

the very first thing you should know is that since this equation's

later you will find that equations like

ok answer to your question

first try inserting

that is the point where the graph intercepts the

like wise you can try inserting more values for

it's just simple as that! good luck =)

graph{x-y=10 [-10, 10, -5, 5]}

see explanation

#### Explanation:

This is the equation of a line. When the line crosses the x-axis , it's y-coordinate will be zero. To find the x-intercept substitute y = 0 into the equation.

let y = 0: x - 0 = 10 → x = 10 → (10,0) is a point on line.

Similarly when the line crosses the y-axis it's x-coordinate will be zero.

Let x = 0: 0 - y = 10 → y = -10 → (0,-10) is a point on the line.

2 points are enough to draw the line , although a 3rd point is useful in aligning the points.

For this choose any value for x/y and substitute into equation.let x = 2: 2 - y = 10 → -y = 8 → y = -8 and (2,-8) is a point.

Now plot (10,0), (0,-10) and (2,-8) and draw a straight line through them.

Here is the graph of x-y = 10

graph{x-10 [-20, 20, -10, 10]}
