Question

Determine whether the graphs of the given equations are parallel, perpendicular, or neither y=-2y=9

Answer 1

the equation of a line in the slope intercept form is given by:

`y=mx+b`

for:

`\begin{gathered} y=-2 \\ m=0 \end{gathered}`

For:

`\begin{gathered} y=9 \\ m=0 \end{gathered}`

Two lines are parallel if :

`\begin{gathered} since\colon \\ 0=0 \\ \\ m1=m2 \end{gathered}`

The lines are parallel
