Write the equations of two parallel lines with negative slopes.

Consider the line equation is $\"\"$ .

Hence the slope of the line equation is $\"\"$ ,then parallel line slope is $\"\"$ .

Let the point is $\"\"$ .

Point slope form of the equation of a line is $\"\"$ .

Find the slope-intercept of parallel line equation.

$\"\"$ (Formula for Point-slopeintercept)

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

$\"\"$ (Distributive property: $\"\"$ )

$\"\"$ (Simplify)

Therefore, the slope intercept form of the line equation is $\"\"$ . $\"\"$

The line equation is $\"\"$ and parallel line equation is $\"\"$ .
