1. A city map is laid out on a coordinate plane. Elm Street is described by the line x + 2y = 6. Oak street intersects Elm Street at an right angle. Which of the following could be the equation for Oak Street?
a. 2x + y = 5
b. 2x + y = 3
c. x + 2y = 4
d. x  2y = 8
My answer: d?
2. Which expression is NOT equivalent to 3/x1?
a. (3x + 6)/(x^2 + x  2)
b. (3x  3)/(x^2  2x + 1)
c. (3x + 3)/(x^2  1)
d. (3x  3)/(x  1)
My answer: d?

1. the slope of x+2y = 6 is 1/2
so we are looking for a line with slope +2
so anything starting with 2xy = .... or 2x + y = ... will do.
looks like b) to me
2.
They all factor and simplify
a) 3(x+2)/((x+2)(x1)) = 3/(x1) , x ≠ 2
b) 3(x1)/((x1)(x1)) = 3/(x1) , x ≠ 1
c) 3(x+1)/((x+1)(x1) = 3/(x1) , x≠ 1
so far they are all equal
so if there is an answer it must be d)
d) 3(x1)(x1) = 3 , which is not the same as 3/(x1)
you were right with d)
