Find the equation of a line that is parallel to the line y

Find the equation of a line that is parallel to the line y = - 15x and contains the point (6, - 3). Y = (Type your answer in slope-intercept form.)

given line y =-15x

slope of given line m =-15

given that our required line is parallel to given line

we know that slopes of parallel lines are equal

so slope of required line is m =-15

given required line contains (6,-3)

equation of required line using point slope form is y-(-3)=-15(x-6)

y+3=-15x+90

y=-15x+87

equation of required line is y =-15x+87
