Please provide all steps as im very confused about what to do first of all find the gradient for the points (-2,3) and (3,7). perpendicualr gradient is So the line for the perpendicular becomes Now use (4,-1) to find c and you will have your answer....
Thank you so much!! Is it alright to have the final equation as y+1 = -5/4 (x-4)?
Its ok, depends what form you are asked to provide your answer in. Your answer is in the form which is fine. If you need to find the y-intercept which is common you would need to find c as follows
