Question

y=4x-1 and y=-1/4x+1000 is it parallel, perpendicular or neither

Answer 1

You can answer that if you knowthe relationship between the slopes of two perpendicular lines.

Answer 2

perpendicular :4 multiply by -1/4 is -1

Answer 3

\[m_1: slope line1\]
\[m_2: slope line2\]

Answer 4

if \[m_1\times m_2 = -1\] then the lines are perpendicular.

Answer 5

\[m_1 = 4\] and \[m_2 = -\frac{1}{4}\]

Answer 6

So, \[m_1\cdot m_2 = -4\cdot\frac{1}{4}=-1\]

Answer 7

Perpendicular

Answer 8

Did you get that?

Answer 9

yeah

Answer 10

medal then?
