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.
It is a straight line with gradient -A/B and intercept C/B.

The lines are parallel.
A graph that has 1 parabolla that has a minimum and 1 positive line.

y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
