Given the equations:
[tex]\begin{gathered} y=2x+6 \\ y=\frac{1}{2}x+3 \end{gathered}[/tex]The equation has the form of slope - intercept form which is like:
[tex]y=m\cdot x+b[/tex]Where m is the slope and b is y- intercept
So,
The slope of the first equation = 2
The slope of the second equation = 1/2
The graphs of the equations are parallel when the slopes are equal
The graphs of the equations are perpendicular when the product of the slopes = -1
so,
the slopes are not equal
The product of the slopes = 2 * 1/2 = 1
So, the graphs of the equations are neither parallel nor perpendicular.
