Question

Y=2×+7 and y=2×-4 are these parallel, perpendicular or neither

Answer 1

You can see that both equations are written in the form

`y=mx+b`

Where m indicates the slope of the line and b the intercept of the line with the y axis.

`\begin{gathered} y=2x+7 \\ \text{and} \\ y=2x-4 \end{gathered}`

As you can see, both lines have slope m = 2. By definition, two lines are parallel if they have the same slope.

Therefore, the two lines are parallel.
