Question

What is the slope is a line that is perpendicular to the graph of y=2x+5Mark only one oval -1/21/22-2

Answer 1

Step 1

Given;

`y=2x+5`

Required; To find the slope.

Step 2

`\begin{gathered} y=mx+c \\ m_1=slope=2 \\ c=y-intercept \\ y=2x+5 \\ For\text{ perpendicular lines }m_1(m_2)=-1 \\ \end{gathered}`
`\begin{gathered} 2(m_2)=-1 \\ m_2=-(1)/(2) \end{gathered}`

Answer;

`slope\text{ of the perpendicular line required=}-(1)/(2)`
