The line equation in slope-intercept form is $\"\"$ , where m is the slope

and b is the y-intercept.

Write the equation 2 in slop-intercept form.

$\"\"$ (Subtract 2x from each side)

$\"\"$ (Apply additive inverse property: $\"\"$ )

$\"\"$ (Apply additive identity property: $\"\"$ ) $\"\"$

Next find the slope of the equations.

Slope of the first equation is -2

Slope of the second equation is -2 $\"\"$

If two lines are parallel, their slopes must be equal.

Slopes of the lines are equal. So, the lines are parallel. $\"\"$

The lines are parallel.
