X - y = -3
y = x + 3.......slope = 1, y intercept = (0,3)
to find x int, sub in 0 for y and solve for x
x - y = -3
x - 0 = -3
x = -3....so the x intercept = (-3,0)
plot ur points (0,3) and (-3,0)......now start at (-3,0)....and since ur slope is 1, go up one, and to the right 1, and up 1, and to the right 1.....do this over as many times as needed and u should cross the y axis at (0,3)
Area under ALL probability distribution curves is 1.0, because all possible outcomes are taken into account.
Area is base x height divide by 2
6x13=78
78 divide by 2 is 39

Relative max on (2)
Relative min on (-2)
