Question 164866
This is a rather simple problem once you understand what it is asking.

the y-intercept of a point is the y value when x=0
the x-intercept of a point is the x value when y=0

x-y=3
x-intercept:
when y=0 x=?
substitute 0 for y
x- y =3
x-(0)=3 or x=3
therefore the x-intercept of x-y=3 is the point (3,0)

y-intercept
when x=0 y=?
substitute 0 for x
 x -y=3 
(0)-y=3 or -y=3
divide both sides by -1 and you get y=-3
therefore the y-intercept of x-y=3 is the point (0,-3)

Graph these two points and then draw a straight line between them and this is your graph.
