In this video, we are going to look at parallel lines. To find the equation of parallel lines, we still use the y=mx + c equation, and because they have the same gradient, we know straight away that the gradient ‘m’ will be the same. We then just need to find the missing y-intercept ‘c’ value. VISI
Plants have developed responses called tropisms. A tropism is a growth in response to a stimulus; so light and water in the plant’s case. There are different types of tropisms: Positive tropisms are when growth is towards the stimulus - so the plant growing towards the light to maximise the stimul
