y=mx+c where m = gradient and c = the y-intersect hence gradient= 6 and y-intersect=2

y=mx+c where m is the gradient and c is the y-intersect hence gradient=6 and y-intersect = 2 . this can also be found by differentiating the equations dy/dx = 6 and setting x=0 to find the y value.

It is the process which uses Carbon dioxide, Water and sunlight to produce Sugar (glucose) and oxygen.

Techniques such as P.E.E.L can be used in order to help structure paragraphs in a specific way to help get your point across and expand on the point effectively. P.e.e.l stands for point, evidence, explan...

You're right that x = 4 is a solution to the equation - but the problem is it's not the only solution, x = -4 also works.You have to be careful not to take a shortcut by simply taking the square root of b...
