Question

Two lines are perpendicular. The equation of the first line is y = 4x + 1. Which of the following cannot be the equation of the second line?

Answer 1

Hint :If both lines are perpendicular.use this formula\[\huge{m_1m_2=-1}\]

Answer 2

\[y=mx+c\]where\[y=vertical~axis\]\[x=horizontal~axis\]\[m=slope\]\[c=y-intercept\]try comparing this equation\[y=4x+1~with~y=mx+c~\to~find~the~slope\]Therefore,the slope will be m=4
now u have the value for\[m_1=4\]

Answer 3

plug in into this formula\[m_1m_2=-1\]to find\[m_2\]

Answer 4

so its b right

Answer 5

\[m_2=second~gradient/slope\]

Answer 6

Let me check

Answer 7

\[4m_2=-1\]divide both sides by 4\[m_2=-\frac{ 1 }{ 4 }\]

Answer 8

you're correct :)
