Question

The following lines are parallel:y = 3x + 7y = - 1 / 3x - 1

Answer 1

The equation of a line is given as

`y=mx+b`

Where m is the slope and b is the intercept on the y-axis.

From the equation

`y=3x+7`

The slope m1 = 3

From the equation

`y=-(1)/(3x)-1`

The slope is

`m2=-(1)/(3)`

For parallel, m1 = m2.

But from what we have, m1 is not equal to m2. Therefore the lines are not parallel.
