If (3 , K) and (2, 4k) are two points on a graph of a line and k is not equal to 0, what is the slope of the line?

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
