Perpendicular lines have slopes which are the "negative inverse" of each other. So ever since the given line has a slope of 1/5, then the slope of all the lines perpendicular to it will be - 5. So the equation so far is y = - 5x + b Now find the value of b for the line passing through the given point. The equation y = mx + b has 4 unknowns, and you already have 3 of them. y = 4 (from the given ordered pair) m = - 5 (the negative inverse of the given slope) x = - 5 (from the ordered pair) b ---- Find b Sub in the values in the place of the letters in the equation y = mx + b 4 = ( -5 )( -5 ) + b 4 = 25 + b - 21 = b So now you have the entire equation of the perpendicular line y = - 5x - 21 <-- answer This is a steep downhill line that crosses the y axis way down at - 21. You can test it for accuracy by graphing the problem roughly on a piece of scrap paper to see if the answer is reasonable -- the drawing should look like its equation might be y = -5x - 21.
