Question

What is the slope of a linear that is perpendicular to the line y=-1/2x+5?​

Answer 1

Explanation:

Equation of given line is:

`y = - (1)/(2) x + 5 \\ \\ equating \: it \: with \: y =m_1x + c \\ we \: find \: \\ m_1 = - (1)/(2) \\ let \: m_2 \: be \: the \: slope \: of \: required \: line \\ \\ \therefore \: m_1 * m_2 = - 1( \because \: lines \: are \: \perp) \\ \\ \therefore \: - (1)/(2) * m_2 = - 1\\ \\ \therefore \: m_2 = 2 \\`

Thus, the slope of required line is 2.
