Question 13 • Algebraic Reasoning

Given p is not equal to q is not equal to 0 , what is the equation of the line that passes through the points open paren negative p comma negative q close paren and open paren p comma q close paren ?

Answer
A
y is equal to q
B
y is equal to negative x
C
y is equal to 2 x plus open paren 2 p minus q close paren
D
y is equal to q over p x

Explanation

The slope through (−p, −q) and (p, q) is (q − (−q))/(p − (−p)) = 2q/2p = q/p. The line also passes through the origin, since the two points are opposites, so its equation is y = (q/p)x. This is choice B, “y is equal to q over p x.”
