Question 689014: Find the slope of the line whose equation is 4x+5y=10
problem 1
2) If line g has a slope of -5/2 what is the slope of a line perpendicular to g?
3) Find the equation of a line whose slope is 3 passing through the origon

Thanks if you can help me out

1. 4x + 5y = 10 : solve for y
5y = -4x + 10
y =
slope is
...
2. Perpendicular lines have a negative reciprocal/inverse slope.
A perpendicular line to g will have a slope of
...
3. Using the point (0, 0) or origin and the slope of 3, apply the point-slope formula of
y - 0 = 3(x-0)
