Question
The graph of r = 7/ (3 cos(theta) + 2 sin(theta)) is a line. What is the slope of the line? How do you do this!!!

r = 7/(3cosθ + 2sinθ)
r(3cosθ+2sinθ) = 7
3rcosθ + 2rsinθ = 7
3x+2y = 7
I guess you can handle it from there, yeah?
r(3cosθ+2sinθ) = 7
3rcosθ + 2rsinθ = 7
3x+2y = 7

It says that -2/3 is wrong
Steve
no doubt. Did you try -3/2 ?
3x+2y = 7
2y = -3x + 7
y = -3/2 x + 7/2
3x+2y = 7
2y = -3x + 7
y = -3/2 x + 7/2

Whoops bad math:) Thanks!
