Question

Lines c and d are perpendicular. The equation of line c is y=−12x+1. What is the equation of line d?

Answer 1

y=1/12x+b

Explanation:

To find a perpendicular line, you need to find the negative reciprocal of the gradient in this case its -12x, the negative reciprocal of this is 1/12x we don't know what coordinates this passes through so we just write y=1/12x+b

Hope this helps!!
