The point is and line equation is .

The above equation compare with slope-intercept form

y = mx + b, where m is the slope and b is the y-intercept.

Slope is

If two lines are parallel their slopes are same, .

Apply point-slope form of the line equation is , where

are the coordinates of a point on the line and m is the slope of a line.

              (Substitute )

                    (Product of two same signs is positive)

Apply distributive property: .

  (Subtract 10 from each side)

                        (Simplify)

The slope-intercept form of the line equation is .
