Question

graph the linear equation x-y=4

Answer 1

Easiest way is to ind the x and y-intercepts or "what the other value is when one of them is zero."

If x=0, then x-y=4 -> 0-y=4 -> 0-4=y -> y=-4 so y-intercept at y=-4 or (0,-4)
If y=0, then x-y=4 -> x-0=4 -> x=4 so x-intercept at x=4 or (4,0)

Having plotted those two points, you now have two points to draw a line through. The line should be sloping up to the right and pass through the -4 on the y-axis BELOW the origin (0,0) and then through the 4 on the x-axis.
