Physics how much work does gravity do during this displacement?

A 25 kg air compressor is dragged up a rough incline from r1 =(1.3i+1.3j)m to r2 =(8.3i+5.0j)m, where the y-axis is vertical?

dy = 5.0 – 1.3 = 3.7 m up
dWg = -dy*w = -dy*m*g = -906.5 J

Minus because the gravitational force is opposite the movement.
