Which statement about (y=8x-3) and (y=-8x-3) is correct?

Answer and explanation

Correct answer: Slopes are different and (y)-intercepts are same

A line written as \(y=mx+b\) can be understood by reading the coefficient of \(x\) as the slope and the constant term as the \(y\)-intercept. For \(y=8x-3\), the slope is 8 and the intercept is \(-3\). For \(y=-8x-3\), the slope is \(-8\) and the intercept is also \(-3\). Thus the lines have opposite slopes but meet the vertical axis at the same point.

Therefore their slopes are different, while their \(y\)-intercepts are the same, which is option B. They do not pass through the origin because putting \(x=0\) gives \(y=-3\), not zero. Their slopes are not zero either. The shared constant term is the key observation, while the opposite signs before 8 show that their directions differ.
