Start with the slope
%28-5--2%29%2F%28-3--1%29+=+-3%2F-2+=+3%2F2
...
Use the slope with one point in the point-slope formula
y+-+-5+=+%283%2F2%29%28x--3%29
y+%2B+5+=+%283%2F2%29%28x%2B3%29
y%2B5+=+%283%2F2%29x+%2B+%283%2F2%29%283%29
y%2B5+=+%283%2F2%29x+%2B+9%2F2
y+=+%283%2F2%29x+%2B+%289%2F2%29+%2B+5
y+=+%283%2F2%29x+%2B+%289%2F2%29+%2B+5%282%2F2%29
