Two points determine a line!

With the equation, y-x=3, it is easy to find the y-intercept (where x=0) and the x-intercept (where y=0):

(x,y): (0,3) (-3,0)

Draw a line between these two points and keep on going in each direction.

Definitions:

**y-intercept**: the place where the line crosses the y-axis, at x=0; this point looks like (0,y)

**x-intercept**: the place where the line crosses the x-axis, at y=0; this point looks like (x,0)

For the equation, y-x=3 , the y-intercept is the point (0,3) [note: plug in the values]

the x-intercept is the point (-3,0)
