Question

A coordinate plane with a line passing through (negative 4, negative 4), (0, 0) and (4, 4).
Which is the equation of the graphed line written in standard form?

y = x
x – x minus StartFraction one-half EndFraction y equals 0.y = 0
x – y = 0
y = y equals StartFraction one-half EndFraction x.x

Answer 1

Slope = (4−0)/(4−0) = 1, so the line is y = x. Written in standard form (Ax + By = C) that is

x − y = 0.
