find the slope of: 4x + 5y = 7
5y = -4x + 7
y = (-4/5)x + 7/5
---
slope = (-4/5) = -0.8
---
parallel lines have equal slope:
---
copy and paste this (the given point and the slope of the parallel line):
3, 2, -0.8
---
into the "Point-Slope form: x1 y1 m" input box of this solver:

---
get the slope and the y-intercept of the parallel line from the solver:
---
slope of parallel line = -0.8 = (-4/5)
y-intercept of parallel line = 4.4
---
answer:
write the equation of the parallel line in slope-intercept form:
y = (-4/5)x + 4.4
