The gradients of the two lines must be the same. The gradient is m in the equation: y=mx+c For example: L1: y = 3x – 2L2: 3y – 9x + 5 = 0 First rearrange L2 so it is in the same form as L1 to get:3y=9x-5T...

The cell's chromosomes, attached to spindle fibres, align themselves on the metaphase plate in the middle of the cell.

First step is to understand what it means for lines to be parallel. This is when the gradients of two lines are the same.This is much easier to see when the format of the equations is the same, so lets re...

This is a 6 mark question which requires reasons in the form of three PEE (Point, Evidence, Explain) paragraphs. A model answer could be structured like this:P: Residual bitterness over the Franco-Prussia...
