Question 684635: (x+4)(x-5) If you were to multiply the two factors in the expression which operation would you perform first?

#2 which of the following statements is false?
A. the slope of any horizontal line is 0
B.the slope of any vertical line is 1

You would distribute or FOIL first. Then multiply and combine like terms.

(x+4)(x-5)

x(x-5)+4(x-5)

x^2 - 5x + 4x - 20

x^2 - x - 20

#2 which of the following statements is false?
A. the slope of any horizontal line is 0
B.the slope of any vertical line is 1
C.parallel lines have the same slope
D.the slope can be found using any two points on a straight line

Choice B is FALSE because the slope of any vertical line is undefined.
