The table below represents which equation? x −1 0 1 2
y −10 −6 −2 2

A y = −4x + 2
B y = 4x − 6
C y = −6x
D y = −x − 10

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,
