Use the coordinates of the labeled point to find the point-slope equation of the line.

15
(3,-5)
A. y-3-5(+5)
B. y + 5 = 3(x + 3)
C. y-5= -3(x+3)
D. y + 5 = -3(x - 3)

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
