What’s the equation of a line on a graph with points of (3,-3) (-2,2)?

To find the equation of a line with the points (3,-3) and (-2,2) we first need the gradient of the line. This is found by doing y2-y1/x2-x1 (or y1-y2/x1-x2). So let's call (x1,y1)=(3,-3) and (x2,y2)= (-2,2). So the gradient is given by 2-(-3)/-2-3 = 5/-5 = -1. We know the equation of a straight line is y=mx+c and we have m=-1 so y=-x+c. We can see that we need to find the value of c. By substitu... more

A five sided spinner labelled with sectors p,q,r,s,t is spun 400 times. How do you find the relative frequency?

The relative frequency is given by: Relative frequency = Probability x Number of trials As there are 5 sectors, the probability of obtaining any outcome is 1/5. Therefore, the relative frequency of obtaining for instance ‘q’ (or any of the other letters) would be: Relative frequency = 1/5 x 400 = 80 Hope this helps.

I am trying to go into Investment Banking/Brokering after my A levels. I understand that a mba is desirable however can I get a masters in business administration even if I do finance Bsc as a bachelors?

Yes, it is possible to study for masters after completing a bachelors. If you plan on studying business administration as a masters after your BSc, I would suggest searching for postgraduate courses in this subject. While searching for courses, it would be good to keep in mind important factors such as location, course content - does it have a variety of topics which could enable you to work in... more

How do I find the equation of a line on a graph using the equation y=mx+c?

To find an equation of a line you must know it’s gradient (how steep the line is) to do this you use the formula Y2-Y1/X2-X1 or change in y divided by change in X =gradient to find the y intercept you use the formula y-y1=m(x-x1) this might look confusing but carry on reading so all you do is substitute the values in the formula m= gradient rearranging into y=mx+c
