What is the slope of the line containing points A(4, -1) and B(0, 2)?
A.3/4
B. 4/3
C. -3/4
D. -4/3

The answer is C. -3/4. The slope is rise/run so you start at (0,2), “rise”(technically you go down 3 and that’s why the slope is negative) 3 and “run” 4 to get to the point (1,-4).

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.
