The line x + y = 1 will be defined by the points that satisfy that equation. The x-axis travels horizontally, the y-axis travels vertically.

Step 1. Draw the axes on graph paper. Each line should be an integer.

Step 2. Plot points that satisfy the equation, like (0,1)(1,0)(2,-1)(1,-2)(3,-2)(-2,3)

Step 3. Draw a line through them with a pencil using a straight edge of some sort.

When one of the numbers is zero, that's where it crosses the other axis. You'll find that the line crosses the x-axis at 1 on the y-axis and crosses the y-axis at 1 on the x-axis.

That's a straight line. Here is one way to solve this.Set x = 0, and solve the resulting equation for "y".Also, going back to the original equation, set y = 0, and solve the resulting equation for "x".

This will give you two points; draw a line through them.
