the points on graph are (0,3),(2,0),(-1,-2),(-3,1)
is this the way to work this m=1-(-2)/-3-(-1) =-1/2 m=0-3/2-0=-3/2
this would be a rectangle would like to know if this is correct

There are 4 lines that make up this rectangle/parallelogram. The lines and their slopes are:
(0,3) to (2,0) with a slope of (3-0) / (0-2) = -3/2
(2,0) to (-1,-2) with a slope of (0-(-2)) / (2-(-1)) = 2/3
(-1,-2) to (-3,1) with a slope of (-2-1) / (-1-(-3) = -3/2
(-3,1) to (0,3) with a slope of (1-3) / (-3-0) = 2/3
The lines with equal slopes are parallel to each other. For this figure to be a rectangle, the lines that intersect must be perpendicular to each other which implies that they have slopes which are the negative inverses of each other. The negative inverse of -3/2 is 2/3. So it is a rectangle.
