Write the equation of the line in slope-intercept form with a slope of -6 and a y-intercept of 9.
The slope-intercept form for an equation is: y = mx + b where "m" is the slope and "b" is the y-intercept. So, all you would have to do at this point is substitute. Try that and see what you get so far.
Good luck and nice working with you!
